DR: diabetic retinopathy. Odds ratio for the predictors of worsening of DR in patients with type II diabetes and DR at baseline obtained using multivariate logistic regression analysis, with variables—urine microalbuminuria, urine macroalbuminuria, HbA1c, serum creatinine, duration of diabetes, age at diagnosis, duration of hypertension, cholesterol, HDL, LDL, triglycerides, family history of diabetes, and body mass index.
