In both this study and others [37,38], the urine albumin-to-creatinine ratio showed a positive association with DR, similar to our cohort of both T1D and T2D grouped together (OR 1.01; 95% CI 1.003, 1.02; p = 0.008) but also in the T2D group alone (OR 1.01; 95% CI 1.002, 1.02; p = 0.016). Here, ALB is linked to type 1 diabetes mellitus.
