Sensitivity analyses of association between the LDL-C and myocardial infarction, and stroke stratified by statin non-user (a) and statin user (b); The LDL < 55 mg/dL group was taken as the reference category for the model. Participants were divided into the following categories of LDL-C levels: < 55 mg/dL (reference), 55 to 69 mg/dL, 70 to 99 mg/dL, 100 to 129 mg/dL, 130 to 159 mg/dL, and ≥ 160 mg/dL. Hazard ratios and 95% confidence intervals of myocardial infarction, and stroke according to the low-density lipoprotein cholesterol levels. Adjusted for age, sex, body mass index, alcohol drinking, smoking, regular exercise, income status, fasting glucose levels, hypertension, and duration of diabetes
