Notes |
|
Risk of bias |
Bias |
Authors' judgement |
Support for judgement |
Random sequence generation (selection bias) |
Low risk |
Randomised by coin flip |
Allocation concealment (selection bias) |
Unclear risk |
Insufficient information to permit judgement |
Blinding of participants and personnel (performance bias)
All outcomes |
Unclear risk |
Blinding of participants and treatment personnel not mentioned in report, but unlikely. Insufficient information to make judgement on impact of lack of blinding. |
Blinding of outcome assessment (detection bias)
Falls and fallers |
Low risk |
Falls reported by participants who were aware of their group allocation. Assessor blind to group allocation. |
Incomplete outcome data (attrition bias)

High risk |
