Figure 1 ROC Curve of the RVFRS and Other Univariable Predictors of RV Failure
Table 7 shows the areas under the receiver-operating characteristic (ROC) curve for the predictors. PAS = pulmonary artery systolic; PVR = pulmonary vascular resistance; RA = right atrial; RV = right ventricular; RVFRS = right ventricular failure risk score; RVSWI = right ventricular stroke work index; TPG = transpulmonary gradient.
