Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "The computer‐generated outcome of randomization was automatically e‐mailed to an independent person"
Allocation concealment (selection bias)	Low risk	Quote: "The York Trials Unit independently and remotely conducted simple Web‐based randomization ... The computer‐generated outcome of randomization was automatically e‐mailed to an independent person who passed the participant's case notes on to the contact person for the group to which they had been randomized."
Blinding of participants and personnel (performance bias) All outcomes	High risk	Participants and personnel carrying out the intervention were aware of group allocation
Blinding of outcome assessment (detection bias) Falls and fallers	Low risk	Quote: "Calendars that were not returned within 2 weeks of the end of the month prompted a telephone contact from an independent, blinded interviewer to ascertain whether the participant had fallen." "All reported falls were followed up with a blinded, structured telephone interview to investigate the circumstances and consequences." "Staff of the York Trials Unit inputted questionnaire data which was checked twice for accuracy."
Incomplete outcome data (attrition bias) Falls	Unclear risk	SeeAppendix 3 for method of assessment
Incomplete outcome data (attrition bias) Fallers	Low risk	SeeAppendix 3 for method of assessment
Risk of bias in recall of falls	Low risk	Used postcard diary, mailed monthly. Followed up in 2 weeks if did not send. Participants also provided with toll‐free telephone number so that they could report falls contemporaneously of they sustained multiple falls or had difficulty recalling falls.
