| Summary of Findings | From 199 systematic reviews in over eight English and non-English-language databases, through multiple search platforms, in 2019. The mean number of data sources seen in the systematic reviews was 3.9 (SD 2), with a range of 1–10. Eighteen records (9%) used a single data source to conduct the systematic reviews. Four leading language platforms were seen in the systematic reviews: English (100%), up to 8% used Chinese data sources, and 4% included Spanish or Portuguese. The four most frequently used data sources were: (1) Medline (98%), (2) Embase (65%), (3) Cochrane Library (56%), and (4) Web of Science (33%). The percentage of systematic reviews listing study registries was 30%. |
