Statistics
All demographic information between HD patients and controls was compared using Pearson’s chi-square test. Comparisons between ventricular event rates, ventricular pacing data, and ventricular event rates with respect to dialysis schedule were also compared using chi-square tests. Fisher’s exact test was use to compare average TSH and EF between the two groups, as well as to compare VT event rates between HD and controls given the rarity of the event. Statistical analyses were performed by SAS software (version 9.4, SAS Institute Inc., Cary, NC, USA).
