Data source and searches
Electronic algorithms in combination with controlled vocabulary and
search terms were used to identify relevant randomised controlled trials
(RCTs) and economic evaluations in: i) MEDLINE (via PubMed, February
2020); ii) Cochrane Controlled Trials Register (via The Cochrane
Library, February 2020), and; iii) EMBASE (via Ovid, February 2020).
Search algorithms were adapted to the requirements of each database, and
validated filters were used to retrieve appropriate designs (tables S1
and S2). Additional studies provided by the GDG and previous SR were
also evaluated (figure 1A and 1B).
