Figure 2.

Receiver-operating curves comparing models that include only anti-PLA2R antibody levels to multivariable models that also include clinical variables at each landmark time. The univariable, bivariable, and multivariable models are those from Table 3 and Supplemental Tables 3 and 4. This figure allows comparison, at each landmark time, of the receiver-operating curves for models with anti-PLA2R antibody levels alone with models that include antibody levels and clinical variables. The significant clinical predictor variables (P < 0.05) in the multivariable model at baseline include creatinine clearance, in the multivariable model at 3 months include albumin, and in the multivariable model at 6 months include creatinine clearance and albumin. The C-statistic values for each model are provided in the figure legends. Ab, antibodies; CI, confidence interval; PLA2R, phospholipase A2 receptor; Ref, reference model.
