| Notes |
|
| Risk of bias |
| Bias |
Authors' judgement |
Support for judgement |
| Random sequence generation (selection bias) |
Unclear risk |
"Randomization and concealment were overseen by the study methodologist (B.J.A.)". |
| Allocation concealment (selection bias) |
Unclear risk |
"Randomization and concealment were overseen by the study methodologist (B.J.A.)". |
| Blinding (performance bias and detection bias)
Patients and providers |
High risk |
Patients and providers were not blinded to the interventions. |
| Blinding (performance bias and detection bias)
Assessors |
Low risk |
"...research staff performing the assessments were blinded to the participant’s assigned
condition." |
| Incomplete outcome data (attrition bias)
All outcomes |
High risk |
Attrition was 24% at 1 month, 21% at 3 months and 21% at 6 months. Balanced. Not ITT. No reasons. |
| Selective reporting (reporting bias) |
Low risk |
The published report included all expected outcomes based on the study hypotheses. |
| Other bias |
Unclear risk |
Only self‐reported outcomes. There were no differences between groups at baseline. |
