Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Randomised placebo controlled clinical trial.
Allocation concealment (selection bias)	Low risk	'Subjects were allocated to four study arms. Ten sites had patients randomised to medications or placebo. Eleven sites had patients randomised to medications, placebo or BMT. Treatments were assigned in randomised blocks of nine or 12'.
Blinding of participants and personnel (performance bias) All outcomes	Low risk	'To insure Interviewers remained blind to treatment assignment, caregivers did not discuss any aspects of treatment with the interviewer'. Clinicians had a treatment protocol.
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Paper reports that in no instance was blinding compromised.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Does not state dropout, however, this is reported in the previous paper.
Selective reporting (reporting bias)	Unclear risk	The paper only reports ABID data, however, other outcome measures were used.
Other bias	Low risk	No other forms of bias noted.
