In multivariate linear regression analysis (enter method), we further assessed correlations between CA 125 and functional status (6MWD, WHO-FC, and NT-proBNP) and echocardiographic (LVED, RVED and pericardial effusion) and haemodynamic (SvO2, mRAP, CI, PVR, and PAWP) parameters by adjusting for age, sex, and body mass index. Here, NPPB is linked to pericardial effusion.
