Figure 2. Week-8 Predictors.

Figure 2.

A. Receiver operating characteristic (ROC) plot for week-8 model with C-reactive protein (CRP) and ustekinumab to CRP ratio. The area under the ROC curve in the representative testing set was 0.78 (95% CI, 0.69-0.87). B, Week-8 variable importance plot. The importance of each predictor was computed by identifying nodes in the trees and summing all information provided by the nodes containing the predictor. The higher the importance, the larger the total discrimination provided by the predictor.
