Use and effectiveness of dapagliflozin in patients with type 2 diabetes mellitus: a multicenter retrospective study in Taiwan

To investigate the clinical outcomes of patients with type 2 diabetes mellitus (T2DM) who initiated dapagliflozin in real-world practice in Taiwan. In this multicenter retrospective study, adult patients with T2DM who initiated dapagliflozin after May 1 2016 either as add-on or switch therapy were included. Changes in clinical and laboratory parameters were evaluated at 3 and 6 months. Baseline factors associated with dapagliflozin response in glycated hemoglobin (HbA1c) were analyzed by univariate and multivariate logistic regression. A total of 1,960 patients were eligible. At 6 months, significant changes were observed: HbA1c by -0.73% (95% confidence interval [CI] -0.80, -0.67), body weight was -1.61 kg (95% CI -1.79, -1.42), and systolic/diastolic blood pressure by -3.6/-1.4 mmHg. Add-on dapagliflozin showed significantly greater HbA1c reduction (-0.82%) than switched therapy (-0.66%) ( = 0.002). The proportion of patients achieving HbA1c
