Some concerns |
There was no information on randomisation or allocation concealment. Baseline details were not reported. The summary statement on baseline details suggests that there are no baseline differences that would suggest a problem with randomisation. |
Some concerns |
There was insufficient information on blinding provided. No information reported whether there were deviations from the intended interventions or not. The analysis was appropriate. |
Low risk of bias |
Most people were followed up >90% and reasons for missing outcome data were described. |
Low risk of bias |
There was insufficient information on whether the outcome assessors were aware of the intervention received. By following a clinical protocol, knowledge of the intervention received could only minimally affect the outcome measurement. |
Some concerns |
There was no trial register entry and no published protocol. |
Some concerns |
Due to insufficient information on randomisation, allocation concealment, blinding of participants and health care providers, and lack of a prospectively registered protocol. |
