Gary 2010.

Methods	RCT
Participants	Depressed people with heart failure (NYHA Class II to III) 42% men Age 30 ‐ 70
Interventions	1. Home exercise programme: 12 weekly face‐to‐face home visits to monitor walking and to tailor the exercise prescription. Participants were advised to walk for 3 days per week for 12 weeks, and to increase duration to a maximum of 1 hour for 3 days per week at moderate intensity (n = 20). 2. Home exercise programme plus CBT (n = 18) 3. CBT alone, based on Beck's CBT model. Each session lasted 1 hour. Total number of sessions not stated, but we assume this was 12 because in the combined group they were delivered at the same time as the home exercise programme visits (n = 18) 4. Usual care (n = 17)
Outcomes	HAM‐D, 6‐minute walk
Notes	Small sample size
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Reported as randomised, but no details given
Allocation concealment (selection bias)	Unclear risk	No details given
Blinding (performance bias and detection bias) participants	Unclear risk	Participants were not blinded to treatment allocation; unclear effect on bias
Blinding (performance bias and detection bias) those delivering intervention	Unclear risk	Those delivering treatment were not blinded; unclear effect on bias
Blinding (performance bias and detection bias) outcome assessors	Low risk	"Data collectors were blind to group assessment"
Incomplete outcome data (attrition bias) All outcomes	High risk	68/74 provided outcome data post‐intervention. Classified as high risk, as more than 5% did not provide outcome data
Selective reporting (reporting bias)	Low risk	All prespecified outcomes were reported.
Other bias	Low risk	No other source of bias identified
