OR, odds ratio; CI, confidence interval
^aCardiovascular and cerebrovascular diseases comprised myocardial infarction, congestive heart failure, peripheral vascular disease, cerebrovascular disease, chronic pulmonary disease, and hypertension
^bDigestive system diseases comprised peptic ulcer disease and mild liver disease
^cRenal and metabolic system diseases comprised renal disease and hyperlipidemia
^dMultivariable logistic regressions adjusted for sex, age, income, area of residence, and urbanization, and various systematic comorbidities were run to identify independent factors associated with type 2 diabetes mellitus; p < 0.05 was considered significant
