Model 1: adjusted for age, gender, duration of diabetes, hypertension, systolic blood pressure, diastolic blood pressure, and current smoking. Model 2: adjusted for all of the variables in model 1 plus body mass index, glycosylated hemoglobin, low density lipoprotein cholesterol, high density lipoprotein cholesterol, and triglycerides. Model 3: adjusted for all of the variables in model 2 plus diabetic retinopathy and nephropathy, estimated glomerular filtration rate, current use of insulin and a statin, aspartate aminotransferase, alanine aminotransferase, and alcohol intake.
