Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated random sequence generation.
Allocation concealment (selection bias)	Low risk	Random number sequence was concealed in pre‐sealed individual envelopes.
Blinding of participants and personnel (performance bias) All outcomes	High risk	Due to disparate experimental conditions, blinding of participants and personnel was not possible.
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Primary outcome measure was a clinical scale, applied by a clinician, who was blind to the treatment.
Incomplete outcome data (attrition bias) All outcomes	High risk	Of 77 participants randomised to a treatment, only 43 completed the study. Twenty‐two dropped out after baseline assessment and a further 12 participants did not complete the study.
Selective reporting (reporting bias)	Low risk	The published study is consistent with an earlier conference abstract (Ashman 2012) and the protocol registered on Trialscentral.org. The study was registered on clinicaltrials.gov, study ID: NCT00211835.
Other bias	Unclear risk	‐
