Some concerns |
General comment | In addition to the available pre-proof published version of the article, the study registries were used in data extraction and risk of bias assessment. The protocol and the statistical analysis plan were not available. The target sample size of n=150 specified in the registry was not achieved (actual sample size n=26). There is no change from the trial registries in the intervention and control treatments. Some efficacy outcomes specified in the registries were not reported in the paper,and the primary outcome reported differs in the report and registries. Both adverse events and serious adverse events were not stated as outcomes in the trial registries. |
