Figure 3.

Receiver operating characteristic (ROC) curves to evaluate the predictive value of baseline clinical factors at arteriovenous fistula surgery on the likelihood of initiating hemodialysis within 2 years. For eGFR alone, area under the curve (AUC) was 0.69 (95% confidence interval [95% CI], 0.63 to 0.76; P<0.001). For the multivariable model (including eGFR at surgery, diabetes, GFR trajectory [Traj; change in eGFR during the preceding year], and proteinuria [ratio of urine protein [Upr] to urine creatinine [CR]; expressed as milligrams per deciliter]), AUC was 0.83 (95% CI, 0.77 to 0.88; P<0.001).
