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).
