Interventions	Control arm: None Intervention arm 1: 1) Team changes 2) Patient education 3) Promotion of self‐management Intervention arm 2: 1) Team changes 2) Facilitated relay of clinical information 3) Patient education 4) Promotion of self‐management
Outcomes	1) Statins 2) Antihypertensives (any) 3) Glycated haemoglobin 4) Systolic blood pressure 5) Diastolic blood pressure 6) Low‐density lipoprotein

Notes	—
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Quote: "computer‐generated allocation", but unsure if this included generation of sequence.
Allocation concealment (selection bias)	Low risk	Quote: "computer‐generated allocation."
Patient's baseline characteristics (selection bias)	Low risk	Quote: "characteristics of enrolled patients in all groups were similar at baseline", in text but not in table.
Patient's baseline outcomes (selection bias)	Low risk	Quote: "characteristics of enrolled patients in all groups were similar at baseline." Includes outcomes of interest.
Incomplete outcome data (attrition bias)	Low risk	Intention‐to‐treat analysis done, attrition very low, reasons for loss to follow‐up provided and proportions are unlikely to reflect outcomes.
Blinding of participants and personnel (performance bias) and of outcome assessors (detection bias)	Unclear risk	Primary: HbA1c and blood pressure: measures not described, and blinding of outcome assessor not described. Secondary: outcome assessors not blinded for medication.
Selective reporting (reporting bias)	Low risk	Checked protocol, everything proposed was conducted.
Risk of contamination (other bias)	Low risk	Information not available.
Other bias	Low risk	Information not available.
