Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	"Non‐stratified permuted block randomization process" carried out by blinded investigator using computer software
Allocation concealment (selection bias)	Low risk	"Allocation was unknown to participants and the therapist until the intervention started".
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Evaluator blinded to participant allocation
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Relatively high level of attrition (8/30 in intervention group), but lengthy treatment period (47 weeks) and reasons given. Similar attrition in control group
Selective reporting (reporting bias)	Low risk	Results for all outcomes cited in Methods section were reported.
Other bias ‐ training and supervision	Low risk	Experienced therapist received additional training.
