ALB and type 2 diabetes mellitus: 2. Glycated hemoglobin, fasting plasma glucose, urine albumin to creatinine ratio, and urine microalbumin level were significantly higher in DR patients than in patients without DR 3. In the multivariate logistic regression analysis, high HbA1C was a significant risk factor for the presence of DR at new T2DM diagnosis (OR: 2.372; P < 0.001). HbA1C, FPG, UACR, and urine microalbumin levels showed significantly positive correlations with DR severity
