“…The first two authors independently assessed the methodological quality of the included studies using the Quality Rating Checklist (QRC), which was developed by Visicato et al (2015) based on previous quality assessment tools (Da Costa, et al, 2013; Soh et al, 2011). The QRC was chosen because it enables the quality assessment of non-randomized studies by rating the study’s rationale, hypothesis, study design, participants, selection criteria, recruitment process, sampling method, ethical aspects, drop out rate, sample size, variables of interest, statistical analysis, results, external validity, conclusion, and study limitations.…”
