  1. DAHS = Derby Aboriginal Health Service. PHC = primary health care. HbA1c = glycated haemoglobin. BP = blood pressure. ACR = albumin creatinine ratio.
  2. Australian Aboriginal and Torres Strait Islander patients treated in PHC settings [29, 30, 3437].
  3. Final year of the “DAHS diabetes study” [28].
  4. *Statistically significant difference (P ≤ 0.05) when compared with ACCHS 1.
  5. Approached statistical significance when compared with DAHS (P = 0.05).
  6. **At least half of each participant’s recorded measurements met the recommended target for both systolic and diastolic BP.
