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).
