PHTN: pulmonary artery hypertension, RV: right ventricle, antegrade wave
during systole (S-wave), retrograde wave in late systole (V-wave),
antegrade wave in early-mid diastole (D-wave), and retrograde wave in
late diastole (A-wave)., BSA: body surface area, m: meter, s: second,
ǂ Median and interquartile range (IQR) were presented for non-parametric
variables and the Kruskal-Wallis test was used for comparison.
Comparison between two groups were performed using the Mann-Whitney
test.
† Mean and standard deviation were presented for normally distribute
variables and one-way analysis of variance (ANOVA) was used for the
comparison. The Bonferroni test was used as post hoc test.
