Their results: Quality assessment criteria were applied by two authors to each of the 158 articles, the correlation of the total scores was r (158) = .744 p<.001. First, inclusion (cut-off of >0.75) and exclusion rates were determined for both ratings separately, leading to an overall classification agreement of 78.47%, with 58 articles excluded by both raters(36.70% of the eligible articles) and 66 articles included by both raters (47.77% of the eligible articles). Moreover, 34 articles (21.53% led to divergent decisions. To resolve the divergences, the decisions were compared to the mean rating across the two raters and the decision of inclusion guided by the mean rating (inclusion: > .75;). With this procedure, 11 articles could be assigned to the inclusion category, as the mean rating suggested inclusion, and additionally, the two ratings only slightly diverged (e.g., rater only having a mean rating of .73 and rater two having a rating of .82) or agreement was reached after discussion, and 23 were rejected. This led to a final set of N=77
