You are answering a USMLE-style medical question. Question: A group of researchers decided to explore whether the estimates of incidence and prevalence rates of systemic lupus erythematosus (SLE) were influenced by the number of years it took to examine administrative data. These estimates were not only based on hospital discharges, but also on physician billing codes. For study purposes, the researchers labeled incident cases at the initial occurrence of SLE diagnosis in the hospital database, while prevalent cases were those that were coded as harboring SLE at any time, with patients maintaining their diagnosis until death. Which statement is true regarding the relationship between incidence and prevalence rates during the time period that might be chosen for this specific study? Options: A) Incidence rates will be higher during shorter time periods than longer periods. B) The prevalence of SLE during consecutively shorter time windows will be overestimated. C) The inclusion of attack rates would increase incidence estimates in longer time periods. D) The inclusion of attack rates would decrease incidence estimates in shorter time periods. Reply with ONLY the letter of the correct answer (A, B, C, or D). No explanation.
