Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Computer‐generated |
Allocation concealment (selection bias) | Unclear risk | The project manager for trial used numbered containers to implement the random allocation sequence, and the sequence was concealed until interventions were assigned. However, the method of concealment was not specified. |
Blinding of outcome assessment (detection bias) All outcomes | Low risk | Biochemically validated |
Incomplete outcome data (attrition bias) All outcomes | Low risk | 54.8% of participants lost to follow‐up, but attrition similar between groups |
