73 participants (n1=35 / n2= 38)

|Risk of bias
The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review
|General comment||In addition to the published report (pre-proof), the retrospective registry was used in data extraction and assessment of the risk of bias. The protocol or statistical analysis plan was not available. The study achieved the target sample size specified in the trial registry (n=60). There is no change from the trial registration in the intervention and control treatments. After selecting the samples, none of the participants was aware of randomization and allocation to groups. The evaluator nurse of data recording is from out of the study and questionnaires was provided in the form of coding to him/her. So, the present study is double-blinded (registry). Some outcomes from the report are not mentioned in the registry (e.g. adverse events, mortality).|
