Data are presented as n (%). Data indicate the number of subjects with each genotype and allele (frequency in percent). Odds ratios for different modes of inheritance were calculated. Odds ratios were adjusted for age, age of onset of diabetes, duration of diabetes, systolic blood pressure, diastolic blood pressure, random blood glucose levels, glycated hemoglobin, and body mass index. DR: Diabetic retinopathy; CDR: Controls without diabetic retinopathy; OR: Odds ratio; CI: Confidence interval.
