A Matrix Metalloproteinase-2-Based Nomogram to Assess the Risk of Encapsulating Peritoneal Sclerosis in Peritoneal Dialysis Patients

Figure 3

Calibration plots for the nomogram. The calibration plot shows the performance of the nomogram. Nomogram-predicted probabilities are compared to the observed rates of encapsulating peritoneal sclerosis (EPS). The -axis represents nomogram-predicted probability of EPS. -axis shows an observed rate of the nomogram. A perfect prediction would correspond to a slope of 1 (diagonal 45-degree broken line). The dotted line indicates the prediction of the nomogram (“apparent”), and the solid line indicates bootstrap-corrected nomogram performance.
