| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Low risk | "...randomly assigned...using a minimization procedure that balances the marginal distribution" |
| Allocation concealment (selection bias) | Unclear risk | Whether the treatment assignment was concealed from study personnel and participants was not described |
| Blinding of participants and personnel (performance bias) All outcomes | High risk | Owing to the nature of the intervention, it was not possible to conceal allocation to the intervention from the participants |
| Blinding of outcome assessment (detection bias) All outcomes | High risk | Allocation to the intervention was not concealed from the study personnel |
| Incomplete outcome data (attrition bias) All outcomes | Unclear risk | Analyses were not conducted on an ITT basis and there was substantial attrition from the trial, especially in the intervention arm. However, "...Missing data were dealt with in a number of ways. Simple imputations of missing data for the primary QOL‐related secondary endpoints was undertaken as a sensitivity analysis." |
| Selective reporting (reporting bias) | High risk | Data on several secondary outcomes were not reported. There were subgroup analyses which were not prespecified |
| Other bias | Low risk | The trial appears to be free of other problems that could put it at a high risk of bias |
