Usual practices (control arm) and 2. Intervention practices (intervention arm) |

| Interventions |
Control arm: None Intervention arm 1: 1) Clinician education |

| Outcomes | 1) HbA1c, mean % (SD) Control arm: pre 7.1 (1.3), post 7.1 (2.4) Intervention arm: pre 7.1 (1.3), post 7.1 (2.3) |

| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Not reported. |
| Allocation concealment (selection bias) | Low risk | Cluster. |
| Provider's baseline characteristics (selection bias) | Unclear risk | Not provided. |
| Patient's baseline characteristics (selection bias) | Unclear risk | Not provided in text or table. |
| Patient's baseline outcomes (selection bias) | Unclear risk | Information not available. |
| Incomplete outcome data (attrition bias) | High risk | Information not available. |
| Blinding of participants and personnel (performance bias) and of outcome assessors (detection bias) | Unclear risk | No objective laboratory methods described for HbA1c. |
| Selective reporting (reporting bias) | Low risk | Matches protocol. |
| Risk of contamination (other bias) | High risk | Quote: "The allocation of the usual practice group may have tempted nurses in the usual practice to join courses similar to the one offered in the intervention practices." |
| Other bias | Low risk | Information not available. |
