| Methods |
Effect of follow‐up by a hospital diabetes care team on diabetes control at one year after discharge from the hospital RCT (NA clusters and NA providers), conducted in 1) Division of Endocrinology, Diabetes, and Hypertension, Brigham and Women’s Hospital, Harvard Medical School, Boston, MA. 2) Nurse practitioner, endocrinologist. In United States of America. 2 arms: 1. Control (usual care) (control arm) and 2. Intervention (continued care) (intervention arm) |

| Notes | — | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Not reported. |
| Allocation concealment (selection bias) | Unclear risk | Not reported. |
| Patient's baseline characteristics (selection bias) | Unclear risk | Table 1 ‐ all P values > 0.05, "Baseline characteristics of the two groups were similar", but they also say "Patients included in this study had variable geographical location, insurance coverage and primary care coverage". |
| Patient's baseline outcomes (selection bias) | High risk | Table 1. Baseline HbA1c P = 0.04. |
| Incomplete outcome data (attrition bias) | High risk | 17% lost in intervention (16/93) group, 18% lost in control group. Reasons not provided. |
| Blinding of participants and personnel (performance bias) and of outcome assessors (detection bias) | Low risk | Objective measure for HbA1c, BP, LDL. |
| Selective reporting (reporting bias) | Unclear risk | Retrospectively registered protocol. Methods match outcomes. |
| Risk of contamination (other bias) | Low risk | Unlikely that control patients were contacted by the study team. |
| Other bias | Low risk | None. |
