Abstract
Background Systematic reviews allow health decisions to be informed by the best available research evidence. However, their number is proliferating quickly, and many skills are required to identify all the relevant reviews for a specific question. Methods and findings We screen 10 bibliographic databases on a daily or weekly basis, to identify systematic reviews relevant for health decision-making. Using a machine-based approach developed for this project we select reviews, which are then validated by a network of more than 1000 collaborators. After screening over 1,400,000 records we have identified more than 300,000 systematic reviews, which are now stored in a single place and accessible through an easy-to-use search engine. This makes Epistemonikos the largest database of its kind. Conclusions Using a systematic approach, recruiting a broad network of collaborators and implementing automated methods, we developed a one-stop shop for systematic reviews relevant for health decision making. Supplementary Information The online version contains supplementary material available at 10.1186/s12874-020-01157-x.

Abstract
Helicobacter pylori infection has been implicated as trigger or disease modifier in immune thrombocytopenia (ITP). So, eradication treatment for this agent could have clinical benefits. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified four systematic reviews comprising 40 studies addressing the question of this article overall, including one randomized controlled trial. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded Helicobacter eradication might decrease risk of bleeding in patients with immune thrombocytopenia but the certainty of the evidence is low.
