Methods	RCT
Participants	Setting: Taiwan N = 150 Sample: residents of rural agricultural area (51% women) Age (years): mean 76.5 Inclusion criteria: medical attention for a fall in previous 4 wks, ≥ 65 years Exclusion criteria: none described
Interventions	1. Home‐based exercise training (physiotherapist) 2. Home safety assessment and modification (public health worker) 3. Control: "education". 1 social visit 30 to 40 min every 2 wks for 4 months with fall prevention pamphlets provided (public health worker)
Outcomes	1. Rate of falls Other outcomes reported but not included in this review
Duration of the study	6 months
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Block randomised. Insufficient information to permit judgement.
Allocation concealment (selection bias)	Unclear risk	Insufficient information to permit judgement
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Participants and personnel not blind to allocated group but impact of non‐blinding unclear
Blinding of outcome assessment (detection bias) Falls and fallers	Unclear risk	Quote: "Participants were asked to report their falls by telephone or postcard; they were also contacted by telephone every 2 weeks to ascertain the occurrence of falling". Blinding of assessors not reported.
Incomplete outcome data (attrition bias) Falls	High risk	High risk of bias for both home‐based exercise versus control and home safety intervention versus control. SeeAppendix 3 for method of assessment.
Risk of bias in recall of falls	Low risk	Prospective. Reported falls by telephone or postcard when they occurred. Phoned every 2 weeks to ascertain occurrence of falls.
