Figure 1. Discriminative performance and model weights of a lasso model predicting end-stage heart failure (a composite of death, HTx, and VAD) in patients with DCM.

N.b. heart transplant: HTx, VAD: ventricular assist device, DCM: non-ischemic dilated cardiomyopathy. The c-statistics and 95% confidence intervals are provided as figure annotations, and were estimated using a 1999 iteration bias corrected and accelerated bootstrap. The model weights represent log odds ratio per SD or per class increase for hypertension and NYHA class.
