Notes: JBI methodological quality appraisal checklist to be scored as: Yes = Y; No = N; Unclear = U; Not applicable = NA;
1* Is it clear in the study what is the ‘cause’ and what is the ‘effect’ (i.e. there is no confusion about which variable comes first)?
2* Were the participants included in any comparisons similar?
3* Were the participants included in any comparisons receiving similar treatment/care, other than the exposure or intervention of interest?
4* Was there a control group?
5* Were there multiple measurements of the outcome both pre- and post-intervention/exposure?
6* Was follow up complete and if not, were differences between groups in terms of their follow up adequately described and analysed?
7* Were the outcomes of participants included in any comparisons measured in the same way?
8* Were outcomes measured in a reliable way?
9* Was appropriate statistical analysis used?
