“…In terms of the limitations of the identified studies, there were instances where the studies were not piloted,[14,30,34,53,62,67,68,70,71,74] where ethical considerations[27,30,67] and consent approval[24,27,30,31,41,58,62,67,68,70,73] were not discussed, as well as instances where the sample size was either not stated[68] or the response rate was low [24,27,73,74]. In some of the papers, the outcome measures,[14,15,27,44,45,58,72–74] recommendations for further studies[14,30,34,53,67,71,73] and limitations of the studies[13,45,67,68] were not discussed. These factors may therefore limit the generalisability of our findings.…”
