Indirect bilirubin is inversely associated with diabetic retinopathy risk and is a potential predictive biomarker

Figure 1 Univariate analysis of the associations between factors associated with type 2 diabetes mellitus and the risk of developing diabetic retinopathy. Univariate logistic regression models were constructed to explore the correlations between type 2 diabetes mellitus factors and the risk of developing diabetic retinopathy. ^aP < 0.01; ^bP < 0.001. Statistical significance was determined at a P value < 0.05. OR: Odds ratio; 95%CI: 95% confidence interval; SBP: Systolic blood pressure; DBP: Diastolic blood pressure; ACR: Albumin/creatinine ratio; eGFR: Estimated glomerular filtration rate; AST: Aspartate transaminase; ALT: Alanine aminotransferase; GGT: Gamma-glutamyl transferase; TBIL: Total bilirubin; IBIL: Indirect bilirubin; DBIL: Direct bilirubin.
