A ROC Curves of TRV and VP in Identifying Overt PH. TRV vs. VP, P < 0.001; TRV + VP vs. TRV, P = 0.002; TRV + VP vs. VP, P < 0.001. B ROC Curves of TRV and VP in Identifying Borderline PH. TRV vs. VP, P = 0.240; TRV + VP vs. TRV, P = 0.038; TRV + VP vs. VP, P = 0.331. PH, pulmonary hypertension; TRV, tricuspid regurgitation velocity; VP, ventilatory power
