- Peak-to-peak cardiopulmonary transit time, left ventricular full-width-half-maximum (FWHM) and time-to-peak measurements were significantly longer for PAH patients than for non-PAH patients and healthy controls. Mann-Whitney U test was used to comparison of all three groups: *p<0.01. Wilcoxon rank-sum text was used for individual group comparisons: PAH vs non-PAH: † p<0.05, ††p<0.01; PAH vs. controls: ‡p<0.05, ‡‡ p<0.01.
