2.2. Study selection
Duplicates were removed using EndNote Reference Manager, and manually in
the Rayyan web and mobile app for systematic review. In the first phase,
four blinded and independent authors (BMF, GOR, ETBM, and GNV) selected
an article by title and abstract, applying the eligibility criteria
according to the PICOS question (above) (Supplementary Material S1 -
Table 2). Any disagreement between the reviewers was solved by an expert
reviewer (IGD and JSR). Next, the full texts of the selected studies
were retrieved and independently assessed for eligibility by four
reviewers (BMF, GOR, ETBM, and GNV). Any disagreement was resolved
through discussion between the reviewers and an independent expert (IGD,
JSR, IFK, and EDM).
