  1. Multiple regression analyses and trend test analysis were used. The regression was adjusted for age, sex and diabetes duration, smoking, systolic blood pressure, body mass index, angiotensin-converting enzyme inhibitors/angiotensin receptor blocker, fasting plasma glucose, glycosylated hemoglobin A1c, triglyceride, estimated glomerular filtration rate.
