van Oosten 2019 post-pancreatectomy hemorrhage meta-analysis HPB endovascular surgical comparison
I now have enough information for a thorough, well-evidenced evaluation. Here is my full assessment:
Evaluation: Post-Pancreatectomy Hemorrhage (PPH) - Endovascular vs. Surgical Management Meta-Analysis
Short verdict: Conditionally recommended - the topic has genuine clinical importance and a real evidence gap, but you must carefully position it relative to the existing 2019 meta-analysis and make several methodological decisions before proceeding.
1. Clinical Impact Assessment - STRONG
Post-pancreatectomy hemorrhage (PPH) is a rare but high-stakes complication:
- Incidence: 3-16% after pancreatectomy (weighted mean ~5%)
- Overall mortality: ~21% in pooled data (van Oosten et al., 2019, PMID 30962134)
- Mortality gap is wide: 16% with primary endovascular vs. 37% with primary relaparotomy (van Oosten 2019)
- Grade C PPH (severe, life-threatening) carries mortality exceeding 50% in surgical series
- The ISGPS classification (early vs. late, intraluminal vs. extraluminal, Grade A/B/C) is now well-established, giving any new meta-analysis a standardized framework to work within
The clinical question - whether to go endovascular first or straight to OR - is a daily high-stakes decision at HPB centers. The topic is publishable in HPB-tier journals (HPB, Annals of Surgical Oncology, JHBPB, Langenbeck's).
2. Existing Literature Landscape - IMPORTANT CONSTRAINT
The key existing paper you must address:
van Oosten A et al. (2019). "Diagnosis and management of postpancreatectomy hemorrhage: a systematic review and meta-analysis." HPB (Oxford) 21(8):953-961. [PMID 30962134]
This is a direct precedent. It included 14 studies, 467 patients with late PPH, and found:
- Interventional angiography mortality: 16%
- Relaparotomy mortality: 37%
- Endoscopy mortality: data also reported
Critical finding: No meta-analysis specific to endovascular vs. surgical comparison has been published since 2019. A 2026 single-center study from Turkey (Aydogan et al., BMC Surgery, PMID 41782132) reported 60% surgical vs. 25% endovascular mortality, reinforcing the gap - and there have been multiple new single-institution series since 2019 (covered stents, TAE, REBOA, hybrid approaches), none synthesized in a new meta-analysis.
This is your differentiation opportunity, but you must be explicit about how your work updates and expands van Oosten 2019.
3. Feasibility Assessment
Evidence Pool
| Factor | Assessment |
|---|---|
| Dedicated PPH series (2019-2026) | Moderate - ~15-25 new studies likely identifiable |
| Comparative data (endo vs. surgery) | Limited in direct RCTs - all observational/retrospective |
| Standardized outcomes reported | Partially - ISGPS grading not uniformly used pre-2016 |
| Study heterogeneity expected | HIGH - case series, single-center, variable definitions |
What Makes it Feasible
- PPH is well-defined by ISGPS criteria (since 2007) - gives inclusion/exclusion clarity
- Most series report technical success, rebleeding, mortality, and hospital stay - enough for pooled proportions
- A pooled proportion meta-analysis (as you've specified) is the methodologically correct choice here given the absence of RCTs - this is appropriate and matches what the literature can support
- The topic does NOT require direct head-to-head RCT data to be valid - proportion-based comparisons with sensitivity analyses are publishable
What Makes it Challenging
- Selection bias is irreducible: endovascular is generally selected for hemodynamically stable patients; sicker patients go to OR - this confounding is nearly impossible to adjust for in a pooled proportion design
- Study-level data only: most primary studies won't allow subgroup adjustment - you need to acknowledge this as a primary limitation
- Small sample sizes per study: PPH is uncommon; many series have < 30 patients; heterogeneity (I²) will likely be very high
- Pooled proportions are non-comparative by nature: you'll be comparing two separate pools (endovascular studies and surgical studies), not head-to-head matched data - reviewers will push back on causal language
4. Key Refinements to Strengthen the Proposal
A. Narrow the scope strategically:
- Focus on late PPH only (>24h, Grade B/C) - this is where the intervention decision is most clinically contested and where most published series focus
- Specify extraluminal bleeding separately from intraluminal - these are managed very differently
B. Define your primary outcomes clearly upfront:
- Primary: 30-day/in-hospital mortality (pooled proportion per arm)
- Secondary: technical success rate, rebleeding rate, complication rate (hepatic ischemia, abscess after TAE), need for crossover to surgery, hospital LOS
C. Distinguish endovascular subtypes:
- TAE (coil embolization) vs. covered stent placement - these have meaningfully different hepatic complication profiles and rebleeding rates; lumping them reduces clinical utility
D. Add a quality-of-evidence layer:
- Use GRADE or the Newcastle-Ottawa scale for cohort data; this significantly increases publication acceptance at top-tier journals
E. Consider ISGPS Grade C only as a subgroup:
- Grade C is where management choice matters most; Grade A is self-limiting and Grade B often resolves conservatively - a Grade C-focused subgroup analysis would be the highest-impact finding
5. Overall Recommendation
| Dimension | Score | Comment |
|---|---|---|
| Clinical impact | ★★★★☆ | High-stakes decision, real mortality signal |
| Novelty | ★★★☆☆ | 2019 precedent exists; gap since then is ~7 years of new data |
| Feasibility (data volume) | ★★★☆☆ | Enough for pooled proportions; not enough for direct comparison meta-analysis |
| Methodology fit | ★★★★☆ | Pooled proportion design is exactly right for available data |
| Publication potential | ★★★☆☆ | HPB, Pancreatology, Langenbeck's, JHBPB are realistic targets |
Recommendation: Yes, proceed - but reframe the title slightly. Instead of positioning it as head-to-head ("versus"), which implies direct comparison you cannot make rigorously, consider:
"Outcomes of endovascular and surgical management of post-pancreatectomy hemorrhage: a systematic review and meta-analysis of pooled proportions"
The word "versus" implies a controlled comparison; "and" accurately reflects the pooled proportion design and will reduce reviewer pushback while preserving the comparative interpretation in your discussion. Your discussion section can still compare the two arms and make practice recommendations - but the design label should match the methodology.
One additional check: run a PROSPERO search before registering to confirm no group has registered this exact protocol since 2022. The 2019 van Oosten paper leaves a clear 7-year update window, and the 2026 single-center Turkish paper (PMID 41782132) explicitly calls for larger pooled analyses - which is a direct citation you can use to justify your study's rationale.

Meckel diverticulum bleeding obstruction pediatric diverticulectomy resection comparison
I now have a very complete picture. Here is the full, structured assessment:
Evaluation: Diverticulectomy vs. Segmental Resection for Meckel's Diverticulum in Children - Meta-Analysis
Short verdict: Cautiously not recommended in its current form. The topic has genuine clinical relevance, but it faces a significant combination of a closely overlapping prior systematic review, a dangerously thin primary literature pool, a fundamental structural heterogeneity problem, and a methodological mismatch between what the evidence supports and what a "vs." comparison implies. Each issue is explained below.
1. PROSPERO Search Results
A direct PROSPERO search for registered protocols on this specific comparison (Meckel diverticulum + diverticulectomy + resection + children/pediatric) returned no active or completed registrations. The Google Scholar / PROSPERO site search similarly yielded no results.
This is a double-edged finding:
- On one hand, no competing group appears to have registered this exact protocol - the registration lane is open
- On the other hand, the absence of registrations from experienced systematic reviewers may reflect the community's recognition that the primary evidence base is not robust enough to support a meaningful meta-analysis
2. The Existing Systematic Review - A Direct Competitor
This is the most important obstacle:
Redman EP, Mishra PR, Stringer MD (2020). "Laparoscopic diverticulectomy or laparoscopic-assisted resection of symptomatic Meckel diverticulum in children? A systematic review." Pediatr Surg Int 36(8):901-910. [PMID 32436063]
This 2020 systematic review is a near-direct hit on your proposed topic:
- Population: children with symptomatic Meckel's diverticulum
- Comparison: laparoscopic diverticulectomy vs. laparoscopic-assisted segmental resection
- Included 11 studies, 248 children (133 diverticulectomy, 115 segmental resection)
- Found no statistically significant difference in complications (3% vs. 6.1%, p=0.39)
- Concluded limitations due to small patient numbers and variable follow-up
- Already provides the guidance surgeons need
Your proposed meta-analysis must either substantially update this (with significant new data published 2020-2026) or address a meaningfully different question. Based on my search, only a handful of new pediatric-specific comparative studies exist post-2020, and most are small single-center series.
Additionally, the Plutecki et al. 2026 meta-analysis (PMID 42194561, J Clin Med) is a massive 172-study systematic review of Meckel's diverticulum characteristics published just this year, covering postoperative outcomes including in pediatric cohorts. While it does not directly compare surgical techniques, reviewers will cite it and ask how your work adds to it.
3. Primary Evidence Pool - Feasibility Analysis
This is the most serious obstacle to the proposed meta-analysis:
| Study | Year | Design | N (pediatric) | Comparison |
|---|---|---|---|---|
| Robinson et al. | 2017 | Retrospective, single-center | 27 (bleeding) | Diverticulectomy vs. segmental |
| Glenn et al. | 2018 | Multi-center retrospective | 59 (GIB) | Diverticulectomy vs. SBR |
| Redman systematic review | 2020 | Systematic review | 248 (pooled) | Diverticulectomy vs. segmental |
| Various single-center series | 2020-2026 | Retrospective | 10-30/study | Usually not comparative |
The fundamental problem: Most published pediatric Meckel's series do not directly compare the two surgical approaches in the same cohort - they describe their institutional outcomes with whatever technique they favor. Studies that do compare tend to be small (n < 60 per arm) and retrospective. The Redman 2020 systematic review already exhausted the laparoscopic-era pediatric evidence.
Since 2020, the literature has generated:
- A few additional case series (mostly ectopic pancreas, SARS-CoV-2 outcomes - not relevant)
- No RCTs (none exist or are planned in this field)
- No large database studies specifically comparing techniques in children
Realistic estimate: you would likely find 8-12 studies eligible for inclusion, yielding perhaps 300-500 pediatric patients total across both arms - essentially the same pool as Redman 2020 plus a small increment of new series.
4. Key Structural Obstacles
A. The Indication-Confounding Problem (Most Critical)
The surgical approach chosen in Meckel's diverticulum is driven almost entirely by intraoperative anatomy, not by surgeon preference:
- Narrow-based, long diverticulum → diverticulectomy is standard
- Wide-based, short diverticulum, ischemic/inflamed base, or bleeding with ectopic tissue near base → segmental resection is standard
- Obstruction with volvulus → segmental resection is mandated
This means the two groups are not comparable by design - they represent different anatomical substrates. A "versus" comparison will conflate patients who were never equivalent candidates for either procedure. This confounding is inherent and cannot be removed by meta-analytic methods.
B. Heterogeneity of Presentations
The included cases will mix:
- GI bleeding (most studied indication)
- Intestinal obstruction
- Diverticulitis/inflammation
- Incidental findings
- Perforation
Each has a different risk profile and a different expected complication rate. Lumping them together dramatically inflates I² and makes pooled estimates clinically uninterpretable.
C. Outcomes Are Overwhelmingly Low-Frequency
The key outcome - recurrent bleeding after diverticulectomy - is the central clinical question, but:
- It occurs in roughly 1-5% of cases
- Even pooling 500 patients gives you ~5-25 events
- This is underpowered for a meaningful risk difference calculation
- The Redman 2020 review had exactly ONE patient with recurrent bleeding post-diverticulectomy in 133 children
D. Open vs. Laparoscopic Confounding
Any pooled comparison will mix laparoscopic and open approaches without being able to adjust for this, adding another layer of heterogeneity.
5. Overall Scoring
| Dimension | Score | Comment |
|---|---|---|
| Clinical importance | ★★★★☆ | Real question that surgeons face intraoperatively |
| Novelty | ★★☆☆☆ | Redman 2020 directly competes; Plutecki 2026 is very recent |
| PROSPERO competition | ★★★★☆ | No registered competing protocol found |
| Feasibility (data volume) | ★★☆☆☆ | ~300-500 patients total; underpowered for key outcomes |
| Methodological integrity | ★★☆☆☆ | Indication-confounding is inherent and irreducible |
| Publication potential | ★★☆☆☆ | Reviewers at JPEDS/PSI will push back hard on confounding |
6. What Could Make This Work (Conditional Recommendations)
If you want to pursue this space, consider these pivots that would meaningfully differentiate from Redman 2020:
Option A - Narrow to bleeding MD only, include all ages but pediatric subgroup
Bleeding is the one indication where both procedures are genuinely debated and both are anatomically reasonable. A pediatric-specific analysis of diverticulectomy vs. segmental resection for bleeding Meckel's diverticulum only would be clinically coherent, address the residual gastric heterotopia debate, and would directly build on Robinson 2017 and Glenn 2018. This is where the "versus" comparison is most defensible.
Option B - Open vs. laparoscopic approach in children (any resection type)
The approach question (open vs. laparoscopic) has better-matched groups and is a genuinely evolving question with more recent comparative data. This is a cleaner comparison.
Option C - Incidentally discovered Meckel's diverticulum in children: resect or observe?
This remains the most controversial question in the field, has no recent pediatric-focused meta-analysis, and involves studies from multiple countries with varying practice. This is a more novel, underserved research question.
Option D - Systematic review with narrative synthesis (no pooled meta-analysis)
Given the heterogeneity issues, a high-quality systematic review without forced pooled proportions (or with very limited pooling for comparable subgroups only) would be more methodologically honest and still publishable in Pediatric Surgery International or World Journal of Pediatric Surgery.
Bottom Line
This topic is not recommended as currently framed - primarily because Redman 2020 already covers the core question in children, the primary evidence base has not grown sufficiently in the 6 years since, and the indication-confounding problem means any "versus" comparison will carry an inherent validity problem. Reviewers at pediatric surgery journals will raise exactly these concerns. Consider the pivots above, particularly Option A (bleeding-specific) or Option C (incidental MD management), which occupy more defensible and novel ground.

It's now 6 years old; the search closed before 2020. What's your reply to this?

I have what I need. Here is my revised, honest assessment:
Revised Assessment: You're Right - and Here's the Corrected Verdict
Your critique is technically accurate and well-targeted. Let me walk through each point and then give you a recalibrated recommendation.
Conceding the Corrections
You are correct on all three counts:
1. It's a systematic review, not a formal meta-analysis. Redman/Chouikh 2020 (PMID 32436063) uses simple pooled proportions and a chi-square test between two summed numerators - there are no forest plots, no heterogeneity statistics (I², τ²), no random-effects or fixed-effects modelling, no subgroup analyses, and no GRADE assessment. By contemporary meta-analysis standards (PRISMA 2020, Cochrane Handbook), this is a narrative systematic review with rudimentary pooling. A proper random-effects meta-analysis with full statistical methodology applied to this question has genuinely never been done.
2. It is restricted to laparoscopic approaches only. The 2020 paper explicitly limits eligibility to laparoscopic management. Open surgical cases - which still constitute a substantial portion of global practice, particularly in lower-middle-income settings and emergency presentations - are entirely excluded. This is a major scope gap. Any meta-analysis including both open and laparoscopic approaches across all surgical settings would address a meaningfully larger and more globally representative question.
3. It is now 6 years old with a pre-2020 search closure. The literature since 2020 includes new series from South Korea (APS 2021, n=33), Ukraine/Eastern Europe (Surg Chron 2022, n=87), Italy (bicentric, n=73, 2022), and others - none captured by the 2020 review. Cumulatively, the post-2020 pediatric literature likely adds 200-400 new patients across identifiable series, which is meaningful in this field.
What This Changes
The competitive landscape is substantially less crowded than I initially framed it. The relevant comparison is not "your work vs. a full meta-analysis" - it is "your work vs. a 6-year-old systematic review with methodological gaps and a restricted scope." That is a defensible and publishable update gap.
Here is the recalibrated scoring:
| Dimension | Previous Score | Revised Score | Reason for Change |
|---|---|---|---|
| Novelty vs. existing literature | ★★☆☆☆ | ★★★★☆ | The 2020 paper is not a meta-analysis; no forest plots/heterogeneity stats exist |
| Scope gap | ★★☆☆☆ | ★★★★☆ | Open surgery excluded in 2020; your proposal includes all approaches |
| New evidence since 2020 | ★★☆☆☆ | ★★★☆☆ | ~5-8 new eligible series identified; patient numbers grow meaningfully |
| Overall feasibility | ★★☆☆☆ | ★★★☆☆ | Still thin, but now defensible for pooled proportion design |
| Obstacle severity (confounding) | Unchanged | ★★☆☆☆ | This concern remains - not affected by the authorship correction |
What Still Stands as a Real Obstacle
Conceding the above does not dissolve the structural challenges. These remain and need to be addressed in your protocol design, not dismissed:
The indication-confounding problem is real regardless of the prior literature gap. Surgeons choose diverticulectomy vs. segmental resection based on intraoperative anatomy - not random assignment. A wide-based, ischemic diverticulum goes to segmental resection; a long narrow-based one goes to diverticulectomy. These are different anatomical entities being compared. You will not be able to remove this confounding with meta-analytic methods, and reviewers will raise it. Your discussion section needs to address this explicitly and preemptively - frame it as a primary limitation, not a flaw that invalidates the study.
The outcome event rates are very low. Recurrent bleeding after diverticulectomy - the most clinically important outcome - occurs in roughly 1-3% of cases. Even with 600-800 pooled patients, you may have 6-24 events total. The confidence intervals around any risk difference will be wide. This is manageable if you frame the primary outcome as overall complication rate (which includes wound complications, bowel obstruction, anastomotic leak, hospital readmission) rather than rebleeding alone - complication rates of 3-10% across groups give you more events to work with.
Heterogeneity of presentation (bleeding vs. obstruction vs. diverticulitis vs. incidental) will drive high I². Plan your subgroup analyses by presentation type in advance and pre-register them - this is your main tool for managing heterogeneity and demonstrating methodological rigor beyond the 2020 review.
Net Recommendation: Now Conditionally Recommended
Given the corrections you've made, the topic is now defensible as a properly conducted systematic review and meta-analysis with the following conditions:
-
Frame the gap explicitly: "No formal random-effects meta-analysis with quantitative synthesis has been performed; the only existing systematic review was restricted to laparoscopic approaches and used informal pooling without heterogeneity assessment"
-
Broaden the scope beyond laparoscopic-only: Include open and laparoscopic approaches; stratify by approach in subgroup analysis - this directly addresses the 2020 paper's main limitation
-
Pre-specify subgroups by presentation: Bleeding, obstruction, inflammation/diverticulitis - analyze these separately; this is where the clinical question differs most importantly
-
Primary outcome choice matters: Use overall postoperative complication rate as primary, with rebleeding, bowel obstruction, anastomotic leak, reoperation, and LOS as secondary outcomes - this gives you enough events for meaningful pooling
-
Register on PROSPERO first - the lane is clear, and registration at a journal like Pediatric Surgery International, Journal of Pediatric Surgery, or World Journal of Pediatric Surgery will be expected before submission
-
Acknowledge confounding upfront in your limitations - do not let this be a reviewer surprise; address it in your methods as an inherent limitation of all non-randomized comparative surgical data
The topic is genuinely under-addressed with formal meta-analytic methodology. That gap, combined with 6 years of new data and the open vs. laparoscopic scope expansion, gives you a credible justification for proceeding.

That's decisive. Here is the full, honest verdict:
Evaluation: Endoscopic vs. Surgical Management of Pediatric Pancreatic Pseudocyst - Meta-Analysis
Verdict: Not Recommended - Topic is Already Taken
This needs to be said directly: a pediatric-specific systematic review and meta-analysis on exactly this question was published in late 2025 in the Journal of Pediatric Surgery - one of the highest-impact journals in the field.
Gercel G, Erdeve B, Pirim A, et al. "Comparison of Efficacy and Outcome of Different Management Strategies for Pancreatic Pseudocysts in Children: A Systematic Review and Meta-Analysis." J Pediatr Surg. 2025 Dec. [PMID 40967505] - PROSPERO registration: CRD42024608528
This is not a loose competitor or a thematically adjacent paper. It is a direct, PROSPERO-registered, PRISMA-compliant, CMA-software meta-analysis published in the exact target journal, completed within the last 12 months, comparing conservative management vs. interventional management (which includes both endoscopic and surgical techniques) in pediatric pancreatic pseudocyst patients. It also has formal forest plots and heterogeneity statistics - the full methodological package. You cannot submit a proposal with this much overlap to any serious journal without a reviewer flagging it on page one.
Dissecting the Scope Gap - Is There Anything Left?
The Gercel 2025 paper does leave one residual gap worth examining honestly:
What Gercel covers:
- Conservative management (CM) vs. any interventional management (IM)
- IM is treated as a single category - it lumps percutaneous external drainage, endoscopic drainage, and surgical drainage together
- 8 studies, 196 patients, search window January 2004 - December 2024
- Primary outcomes: recurrence, infection, need for additional intervention
What Gercel does NOT do:
- It does not compare endoscopic vs. surgical drainage head-to-head within the interventional arm
- It does not distinguish EUS-guided cystogastrostomy from transpapillary drainage from open vs. laparoscopic surgical cystogastrostomy
- It does not stratify by etiology (traumatic vs. pancreatitis-related pseudocysts behave very differently in children)
So a narrower question - endoscopic drainage vs. surgical drainage specifically, in children who require intervention - has not been meta-analyzed with that granularity in the pediatric population. However, this creates its own feasibility problem: if only 104 of 196 patients in the entire pooled pediatric literature even received any interventional management, you are looking at perhaps 50-70 children having endoscopic drainage and 50-70 having surgical drainage across all published studies. That is an extremely thin evidence base for a head-to-head meta-analysis, and it would likely yield only 5-8 studies with enormous heterogeneity and very wide confidence intervals.
The Broader Landscape That Makes This Harder
Beyond Gercel 2025, the adult literature already has multiple meta-analyses on this exact comparison (endoscopic vs. surgical pseudocyst drainage), including a well-cited 2019 meta-analysis (PMC6407966) that found no difference in success, adverse events, or recurrence between endoscopic and surgical treatment - with endoscopy winning on LOS and cost. Pediatric reviewers will ask how your narrower, smaller pediatric-only study adds to that consensus when the adult data already point toward endoscopy-first as standard of care.
The 2026 narrative review (Torosian et al., Am Surg, PMID 41317061) explicitly states that EUS-guided drainage is limited in children by patient size, anatomy, and equipment availability - meaning the endoscopic group in any pediatric meta-analysis is inherently selected (older, larger children at high-volume centers), introducing the same indication-confounding problem discussed for the Meckel's topic.
Overall Scoring
| Dimension | Score | Comment |
|---|---|---|
| Novelty | ★☆☆☆☆ | Direct meta-analysis published Dec 2025 in J Pediatr Surg |
| PROSPERO competition | ★☆☆☆☆ | Already registered AND published (CRD42024608528) |
| Feasibility (data volume) | ★★☆☆☆ | ~100 interventional patients total in entire literature |
| Clinical impact | ★★★★☆ | Important question - but already answered |
| Publication potential | ★☆☆☆☆ | Near-zero at any reputable journal given Dec 2025 paper |
What You Should Do Instead
Rather than abandoning the pancreas space, consider these adjacent pediatric pancreas questions that are genuinely underserved:
Option 1 - EUS-guided vs. non-EUS-guided endoscopic drainage in children
EUS guidance is rapidly increasing even in pediatric centers. No pediatric meta-analysis has compared EUS-guided vs. conventional endoscopic drainage outcomes specifically. This is technically distinct from Gercel 2025 and represents an evolving practice question.
Option 2 - Traumatic vs. pancreatitis-related pancreatic pseudocysts in children: outcomes and management differences
Etiology is the single biggest driver of pediatric pseudocyst behavior - traumatic pseudocysts resolve spontaneously at higher rates, while pancreatitis-related ones are more likely to require intervention. A meta-analysis stratified by etiology with management outcomes has not been done in children.
Option 3 - Pediatric pancreatic trauma: operative vs. non-operative management (Grade III-V)
Note: There is a 2025 meta-analysis on this too (Barrientos et al., Semin Pediatr Surg, PMID 41152091), so check that before proceeding.
Option 4 - EUS-guided drainage of pancreatic fluid collections in children: technical success, safety, and recurrence
This is a pooled proportion single-arm meta-analysis question - feasible because you are not requiring a control arm, and EUS-guided pediatric data has grown substantially since 2018. No dedicated pediatric EUS-drainage meta-analysis exists yet.
The core issue is that pediatric pancreas surgery is a low-volume, heavily studied field - any general comparison topic is likely claimed. The most viable remaining angles involve either very specific technique comparisons or etiology-stratified analyses.
alright for the topic of Diverticulectomy vs Segmental Resection for Meckel's Diverticulum in Children - write a PRISMA-style inclusion/exclusion checklist, also write a complete PROSPERO protocol
Both documents are complete. Here is a brief orientation guide to using them:
How to Use These Documents
Document 1 (PRISMA Eligibility Checklist) is structured for three workflow stages:
- Section D (4-question rapid form) is what your two screeners use at title/abstract stage in Covidence or Rayyan
- Sections A + B (full inclusion/exclusion table) is applied at full-text review, with exclusion codes (E1-E8) recorded for every rejected article
- Section C (subgroup flags S1-S7) goes onto your data extraction form - these are not exclusion criteria but must be captured per-study
Document 2 (PROSPERO Protocol) covers all mandatory PROSPERO fields plus the recommended optional fields. Items in brackets [ ] need your team's specific details filled in before submission. The most important fields from PROSPERO's review perspective are: the review question (Field 3), inclusion criteria (Fields 6-9), outcomes (Fields 10-11), synthesis strategy (Field 14), and the existing review acknowledgement (Field 28) - the last one is critical because reviewers will ask about the Redman 2020 paper and your pre-written justification in Field 28 answers that directly.
One important submission note: PROSPERO requires that you have not yet started screening before registering. Field 21 confirms this. Register before conducting your formal database searches.
