EVENTS, ARRHYTHMIA
Continuous variables were examined graphically and recorded as mean (± SD) for normally distributed data or median (with 25th and 75th percentile) for non-normally distributed data. Categorical variables were examined by frequency distribution and recorded as proportions. Differences across randomized treatment arms were assessed using analysis of variance, chi-squared test, or Kruskal-Wallis tests, as appropriate.Crude recurrent arrhythmia events were presented as frequency (%) and incidence rate (per 100 patient-days) by treatment groups at baseline, week 6, and the end of study. All analyses were performed using SAS version 9.4 (SAS Institute Inc.) and geepack package in R version 3.4.3 (
