Study characteristics
Methods	Integrated management of type 2 diabetes mellitus and depression treatment to improve medication adherence: a randomized controlled trial Patient RCT, conducted with patients recruited from 3 primary care practices in Philadelphia, Pennsylvania. Study was conducted in a clinical setting. In USA. Two arms: 1) Usual care (control arm) and 2) Intervention (intervention arm)
Participants	Control arm N: 88 Intervention arm N: 94 Diabetes type: type 2 Mean age: NR ± NR % Male: NR Longest follow‐up: 3 months
Interventions	Control arm: None Intervention arm: 1) Case management 2) Patient education 3) Promotion of self‐management
Outcomes	1) HbA1c, mean % (SD) Control arm: pre 7.0 (1.9), post 7.5 (NR) Intervention arm: pre 7.2 (1.8), post 6.5 (NR)

Notes	—
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "…were randomized within each practice by flip of a coin…"
Allocation concealment (selection bias)	Unclear risk	Not described.
Patient's baseline characteristics (selection bias)	Low risk	Information not available.
Patient's baseline outcomes (selection bias)	Low risk	Quote: "HbA1c (P = 0.51)"
Incomplete outcome data (attrition bias)	High risk	Only 2 lost to follow‐up in intervention group ~2%
Blinding of participants and personnel (performance bias) and of outcome assessors (detection bias)	Low risk	HbA1c methods described. Assessors were blinded, physicians blinded to those randomised to usual care.
Selective reporting (reporting bias)	Low risk	Checked protocol and everything proposed was completed.
Risk of contamination (other bias)	Low risk	Information not available.
Other bias	Low risk	Information not available.
