RBP Retinol binding protein, HR Hazard ratio, CI Confidence interval. Model 1 and Model 3 were adjusted for age, gout, hypertension, ALB, Hb, and CT. Model 2 and Model 4 were fully adjusted. Binary RBP was analyzed in Model 1 and Model 2 while continuous RBP was included in Model 3 and Model 4. Model 1 and Model 3 were direct entry models while Model 2 and Model 4 were conditional stepwise forward models
