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.
