| Notes | — | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Low risk | Minimisation. |
| Allocation concealment (selection bias) | High risk | We can predict next sequence with minimisation. |
| Patient's baseline characteristics (selection bias) | Unclear risk | Not reported in text or table. |
| Patient's baseline outcomes (selection bias) | Unclear risk | Not mentioned in text or table. |
| 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 | HbA1c objective measures not described and outcome assessor blinding not described. |
| Selective reporting (reporting bias) | High risk | < 2005 approach used since no protocol. They talked about measuring BP but did not provide results. |
| Risk of contamination (other bias) | Low risk | Information not available. |
| Other bias | Low risk | Information not available. |
