• AMSTAR 1 |
| Aim | To assess the methodological quality of systematic reviews (AMSTAR) that assessed the efficacy of bariatric surgery in diabetic patients across 8 databases from inception up to Dec 2019. |
| Level of Investigation | Descriptive |
| Summary of Findings | The average AMSTAR score in the included 64 systematic reviews was 7:4 ± 1.7. Study protocols not being registered, grey literature not retrieved, incorporation of grey literature as exclusion criteria, and failure to evaluate publication bias and report a conflict of interest were the main causes of low AMSTAR scores. |
