Data Analyses: Statistical analyses will be of explorative and descriptive nature. All analyses will be performed for the total study population who will consist of all patients taking at least one dose of Forxiga. For the safety assessment, occurrences of adverse events (AEs), serious adverse events, adverse drug reactions (ADR), and unexpected adverse drug reactions will be calculated. Severity, actions taken to the surveillance drug, outcome, and causal relationship of AE to the study drug will be analyzed. At the time of the regular reporting and the final reporting, the event count, incidence proportion (that is, the number of patients with any events divided by the number of patients) and incidence rate (number of patients with any events divided by the duration of time patients are followed up in the study) of all the adverse events surveyed during the re-examination period will be summarized, and 95% confidence interval will be presented. Changes in Hemoglobin A1c(HbA1c), Fasting plasma glucose(FPG), and Post-prandial glucose-2 hour(2-hr PPG) before and after administration of Forxiga will be analyzed. At the time of the regular reporting and the final reporting, the event count and effectiveness rate of improvement of lab result (HbA1c, FPG, and PPG), surveyed during the re-examination period will be summarized, and 95% confidence interval will be presented. In order to explore the factors that might influence safety and effectiveness profiles, the cumulative incidence proportion of adverse events and effectiveness rate will be analyzed by patients' background characteristics Sample Size/Power: In accordance with the guidelines provided by the MFDS, at least 3,000 patients will be enrolled. For the overall study population of approximately 3000 patients, the incidence proportion of infrequent adverse events(for example, an incidence proportion of 0.1%) can be estimated with a 95% CI of (0.02, 0.29) (n=3 patients with events).
