Data are presented as mean±sd, median (interquartile range) or %, unless otherwise stated. PAWP: pulmonary artery wedge pressure; PAWPmrc: PAWP as mean across the respiratory cycle; PVR: pulmonary vascular resistance. #: comparisons between all three groups; for pairwise comparisons there was no difference in PVR between precapillary and mixed patients, for all other pairwise comparisons p<0.05; ¶: results only for those with echocardiogram data (precapillary: n=52; post-capillary: n=124; mixed: n=71).
