Flow of study population. Patients were divided into three groups based on the average amount of alcohol consumed before the first diagnosis of T2DM (alcohol consumption behavior): 1) no alcohol consumption (0 g/day), 2) mild alcohol consumption (<20 g/day), and 3) moderate to heavy consumption (≥20 g/day). Alcohol consumption behavior change among those who drank a moderate to heavy amount (≥20 g/day) was defined as the average amount of alcohol consumed within 2 years after new diagnosis of T2DM: 1) constant drinkers (≥20 g/day) and 2) abstainers (<20 g/day); those who did not drink alcohol either before or after T2DM diagnosis were defined as 3) nondrinkers.
