| Study | Year published | RCTs included, n | Theme of the meta-analysis | Summary |
|---|---|---|---|---|
| Musso et al75 | 2012 | 13 | Efficacy and safety of dapagliflozin | – ↓ HbA1c (−0.52%, 95% CI −0.46% to −0.57%; P<0.00001) – ↓ FPG (−18.28 mg/dL [1.01 mmol/L], 95% CI −20.66 [1.15 mmol/L] to −15.89 [0.88 mmol/L]; P<0.00001) – ↓ BMI (−1.17%, 95% CI −1.41 to −0.92; P<0.00001) – ↓ SBP (−4.08 mmHg, 95% CI −4.91 to −3.24) – ↓ DBP (−1.16 mmHg, 95% CI −1.67 to −0.66) – ↓ Serum uric acid (−41.50 μmol/L, 95% CI −47.22 to −35.79) – ↑ Risk genital infections (OR 3.57, 95% CI 2.59–4.93) – ↑ Risk of UTIs (OR 1.34, 95% CI 1.05–1.71) – ↑ Hypoglycemia (mild) when added to insulin (OR 1.27, 95% CI 1.05–1.53) |
