Figure 2. Trends for Publications in Selected Medical and Surgical Specialties, 1995-2017.

Figure 2.

The graph shows the ratio of systematic reviews and meta-analyses (SRMAs) to randomized clinical trials (RCTs) per specialty over time. A ratio of greater than 1 means that more SRMAs than RCTs were published, and a ratio less than 1 means that more RCTs than SRMAs were published. Searches for each specialty used the National Library of Medicine’s medical subject headings for each specialty; for example, obstetrics and gynecology was searched the following phraseology (“Female Urogenital Diseases and Pregnancy Complications”[Majr] OR (“Obstetrics”[Majr] OR “Gynecology”[Majr]) OR (“Obstetric Surgical Procedures”[Majr] OR “Gynecologic Surgical Procedures”[Majr]) OR “Genitalia, Female”[Majr]).
