Percentage of systematic reviewsof a certain domainfor which the combination Embase, MEDLINE and Cochrane CENTRAL reached a certain recall. The highest scoring database combination without Embase is a combination of MEDLINE, Web of Science, and Google Scholar, but that reaches satisfactory recall for only 39% of all investigated systematic reviews, while still requiring a paid subscription to Web of Science. Using both Web of Science and Google Scholar in addition to MEDLINE and Embase increased the overall recall to 98.3%. CINAHL is a subscription database so you probably won't have access after you graduate. The ratio between number of results per database combination and the total number of results for all databases, The ratio between precision per database combination and the total precision for all databases. Syst Rev. Though we occasionally used the regional databases LILACS and SciELO in our reviews, they did not provide unique references in our study.
