INS and retinal disorder: Serum triglyceride levels, hs-CRP levels, and the presence of preproliferative or proliferative retinopathy, microalbuminuria, and macroalbuminuria and the rate of insulin therapy were significantly higher (P = 0.003, P = 0.004, P = 0.046, P = 0.033, P<0.001, and P = 0.007, respectively), and baseline eGFR and the rate of diet only therapy was significantly lower (P = 0.017, and P = 0.033, respectively) in the low bilirubin group (baseline serum total bilirubin levels ≤ 0.5 mg/ dL) than in the high bilirubin group (baseline serum total bilirubin levels > 0.5 mg/ dL).
