Study selection

The search was carried out by two independent reviewers, and, in the absence of agreement, the study was evaluated by a third researcher for final decision making.

The first phase of article selection included the reading of titles and abstracts of all identified studies. After excluding the ones that did not meet the objective of the current study and did not meet the eligibility criteria, duplicate articles were excluded. The remaining ones were then read in full, which led to the exclusion of studies that did not meet the review proposal.
