Blinding of outcome assessment (detection
bias)
All outcomes
High risk Participants recorded falls themselves through the use of a
falls calendar
Incomplete outcome data (attrition bias)
All outcomes
Low risk Incomplete outcome data adequately addressed and unlikely
to seriously alter the results
Selective reporting (reporting bias) Low risk All of the studies’ prespecified outcomes have been reported
in the prespecified way
Reliable ascertainment of falls/fallers outcome
Low risk Participants returned the falls calendar each month. A researcher
telephoned participants who did not return their
calendar
