Sensitivity analysis of primary outcome at the two follow-up periods

	1–6-month follow-up				7–24-month follow-up
Analysis population	N	Difference in mean adherence	95% CI	p Value	N	Difference in mean adherence	95% CI	p Value
Main analysis: all participants with ≥4 months' depot data	108	−6.2%	−13.1% to 0.7%	0.078	116	−5.7%*	−13.1% to 1.7%	0.130
All participants as above, setting adherence to 100% for those discharged to GP	130	−5.0%	−14.7% to 4.7%	0.316	119	−6.2%*	−13.6% to 1.1%	0.097
All participants as above but setting adherence to 0% for refusers	112	−4.9%	−14.3% to 4.2%	0.312	124	−6.4%†	−15.0%—2.1%	0.142

*Simple linear regression model including only a fixed effect for intervention versus control. Clustering by team ignorable as the ICC was −0.05.
†Linear mixed effects model including only a fixed effect for intervention versus control. The model-based ICC was p<0.001. GP, General Practitioner.
