Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote "This study used a quasi‐experimental design" (p. 968)
Allocation concealment (selection bias)	High risk	EPOC describes that CBAs should be scored high for first 2 items
Baseline outcome measurements similar All outcomes	Low risk	Reported in Tables 4 and 5
Baseline characteristics similar	High risk	Site selection based on clinics which "served a large population with severe and persistent mental illness, and provided similar types of services" (p. 986)
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Analyses undertaken "using multiple imputation to replace missing data" (p. 970)
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not reported
Contamination	Low risk	Sites based in 2 US states – Quote "each state included both intervention and control organizations, ensuring that external events would not be confounded with the intervention" (p. 986)
Selective reporting (reporting bias)	Low risk	See Tables 4 and 5
Other bias	High risk	Small sample size, authors did not measure change in the appropriateness of care or client outcomes (p. 974)
