Notes | ||
Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Data checks on IPD provided suggest adequate sequence generation |
Allocation concealment (selection bias) | Low risk | Central telephone |
Blinding (performance bias and detection bias) All outcomes | High risk | Trial was not blinded due to nature of treatment interventions |
Incomplete outcome data (attrition bias) All outcomes | Low risk | IPD provided for all outcomes except late toxicity |
Selective reporting (reporting bias) | Low risk | N/A (IPD supplied for all outcomes except late toxicity) |
Other bias | Low risk | Data checks on IPD provided suggest study is free of follow‐up bias |
