2.5. Study selection process
The author (M.Q.A.) downloaded all references to an EndNote document to remove duplicate items. Then, the author (N.L.C.G.) exported the references to the Rayyan QCRI website. Two authors (R.P.V. and N.L.C.G.) independently screened and selected the records by titles and abstracts. In addition, they evaluated the full-text version of the selected references to determine eligibility criteria. Any disagreement was resolved by mutual discussion between the two reviewers.
