  1. Data are shown as mean ± SD or median (IQR) for continuous outcomes and n (%) for categorical outcomes. P values were based on one-way ANOVA or the Kruskal–Wallis test for continuous outcomes and the Pearson chi-squared test or the Fisher exact test for categorical outcomes. The test utilization in continuous variables was presented with a for ANOVA and b for the Kruskal–Wallis test. ACHD, adult congenital heart disease; BMI, body mass index; CM, cardiomyopathy; HD, heart disease; PH, pulmonary hypertension; VHD, valvular heart disease
