RepOrting standards for Systematic Evidence Syntheses (ROSES) diagram, outlining the process of searching, screening and synthesis for the systematic review. The diagram indicates the inclusion and exclusion process and the numbers of studies retained or excluded at each stage. The ROSES diagram is based on [30]. *Criteria for excluding studies from the quantitative synthesis are non-exclusive (the total sum is less than the numbers reported for each category separately)
