  1. Continuous variables that are normally distributed are reported as mean (standard deviation) and analyzed with the analysis of variance. Continuous variables that are not normally distributed are reported as median (interquartile range [IQR]) and analyzed using Wilcoxon Rank-sum. Dichotomous variables are presented using number (percentage) and analyzed using the Chi-square test
  2. BB beta blocker, SBB selective beta blocker
