Prognostic relevance of ventricular arrhythmias in surgical patients with gastrointestinal tumors

Figure 2 Receiver operating characteristic curves of premature ventricular contractions for combined endpoints. A: Receiver operating characteristic curve of premature ventricular contractions (PVCs) for all-cause mortality among patients with gastrointestinal tumors; B: Receiver operating characteristic curve of PVCs for major adverse cardiovascular events among patients with gastrointestinal tumors. PVC: Premature ventricular contraction; AUC: Area under the curve.
