Data are expressed as mean ± SD or n (%). DM: diabetes mellitus; BMI: body mass index; FH: family history; DR: diabetic retinopathy; CKD: chronic kidney disease. Chi square test was used for qualitative variables. One-way ANOVA for quantitative variables followed by Tukey HSD post hoc test for multiple comparisons. aCompared to the control group; bcompared to microalbuminuria. Bold values indicate significance at .
