The ROC curve for the differentiation of normoalbuminuria and micro- and macroalbuminuria using the urine protein dipstick score, urine protein-to-creatinine ratio, and urine albumin-to-creatinine ratio in non-diabetic patients. Probability (1st, 2nd, 3rd dipstick proteinuria ≥ ( +)): Probability of micro- and macroalbuminuria based on the logistic model using dummy variable dipstick proteinuria ≥ ( +): 1, dipstick proteinuria( ±) (-): 0. Probability (1st, 2nd, 3rd dipstick proteinuria ≥ ( ±)): Probability of micro- and macroalbuminuria based on the logistic model using dummy variable dipstick proteinuria ≥ ( ±):1, dipstick proteinuria(-):0. Probability (1st, 2nd, 3rd uPCR): Probability of micro- and macroalbuminuria based on the logistic model using 1st, 2nd, and 3rd uPCR. The detailed results are listed in Table 3
