This query is about using Google Scholar and Rayyan software for a systematic review — not a clinical/medical content question, so no medical search tools are needed here. This is a research methodology and software workflow question.
Here's a step-by-step guide:
Step 1: Searching on Google Scholar
A. Go to Google Scholar
- Open your browser and go to scholar.google.com
B. Enter Your Search Phrase
Use the search phrases from your systematic review (e.g., Boolean strings like):
("type 2 diabetes" OR "T2DM") AND ("exercise" OR "physical activity") AND ("glycemic control" OR "HbA1c")
- Paste the full phrase into the search bar and press Enter
C. Filter Your Results
On the results page:
- Click "Any time" on the left panel → select your year range (e.g., 2019–2024)
- Optionally tick "Review articles" if needed
- You can also click "Custom range" to set exact years
D. Export the Results to a File
Google Scholar does not allow bulk export directly, so you export 10 results at a time:
- Click the ☰ (menu icon) at the top-left of Scholar → Settings
- Under "Bibliography manager", select "Show links to import citations into" → choose BibTeX or EndNote → click Save
- Go back to your search results
- Click the quotation mark icon (" ") under any article → a citation box opens → click BibTeX (or your chosen format) → copy/save the text
- Alternatively, for bulk export: use the checkbox next to each result → click "Export" (if available in your Scholar version)
Tip: For large exports, consider using Publish or Perish (free software) which lets you export Google Scholar results in bulk directly to a .ris or .csv file — much faster than manual export.
Step 2: Preparing Your File for Rayyan
Rayyan accepts these file formats:
- .ris (most reliable)
- .bib (BibTeX)
- .csv
- .nbib (from PubMed)
So after exporting from Google Scholar (or Publish or Perish), make sure your file is saved as one of those formats.
Step 3: Uploading to Rayyan
A. Create an Account / Log In
- Go to rayyan.ai
- Sign up for a free account or log in
B. Create a New Review
- Click "New Review" (green button on your dashboard)
- Fill in:
- Title of your review
- Description (optional)
- Click "Create Review"
C. Upload Your References
- Inside your new review, click "Upload References" or the upload icon
- Click "Choose File" → select your .ris or .bib file from Google Scholar
- Click "Upload"
- Rayyan will process the file — this may take a few seconds to a few minutes depending on how many articles you have
D. Verify the Upload
- Once uploaded, you'll see your articles listed under "All articles"
- Check the total count matches what you exported
- Rayyan will automatically detect and flag duplicates — you can review and delete them
Step 4: Start Screening in Rayyan
Once all your databases are uploaded (PubMed, Scopus, Google Scholar, etc.):
- Go to "Blind" or "Unblind" mode depending on your review protocol
- For each article, click:
- ✅ Include — if it meets your criteria
- ❌ Exclude — with a reason
- Maybe — if unsure
- Add labels/tags if needed (e.g., "RCT", "observational")
