Abstract

Continuous variables with normal distribution were presented as mean ± standard deviation and compared by independent samples t test, and the multiple groups were compared via one-way analysis of variance. In order to study the BPA learning curve, we divided the 194 times of BPA treatment into four groups (A–D) in chronological order (50 cases in groups A, B, and C, and the remaining 44 cases in group D) and compared the operation time, number of dilated blood vessels and mean time to dilate one blood vessel in each group. [41.87 ± 15.26] mmHg), pulmonary vascular resistance (PVR) (6.50 [3.40, 9.10] WOOD units [WU] vs. 8.78 [5.30, 15.95] WU), brain natriuretic peptide precursor (proBNP) (140.30 [57.76, 601.20] ng/L vs. 387.90 [101.80, 2004.00] ng/L) and World Health Organization (WHO) functional classification (WHO FC) (2.00 [2.00, 2.00] vs. 2.00 [2.00, 3.00]) significantly decreased after the last BPA session (all P < 0.05) [Supplementary Table 2, http://links.lww.com/CM9/A969]. [39.20 ± 16.36] mmHg, P = 0.09), but the difference was not significant, it may be that the sample size is not large enough, and there may be significant differences in the later period as the sample size expands.
