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.
