Data are median (25 and 75% IQR) for continuous variables and frequency (%) for categorical variables.
Microalbuminuria vs. normal; the Cochran-Mantel-Haenszel χ2 and test-based confidence limits controlling for age, type of diabetes, and duration of diabetes. Statistically significant at P < 0.05. DBP, diastolic blood pressure; SBP, systolic blood pressure; TCHOL, total cholesterol; TRIG, triglycerides.
