Statistical analysis
Frequency distribution of categorical variables were reported as frequencies and percentages and compared between groups using chi-squared test (X2). Data were presented as mean (standard deviation) or median (interquartile range) where appropriate. To compare differences of echocardiographic parameters among each ventricular geometry variant, we performed one-way ANOVA or Kruskal-Wallis test wherever it followed parametric distribution. Zidak-test or Dunn’s post hoc test was also used to evaluate differences among ventricular groups.
