Statistical analysis
All continuous variables are presented as mean ± SD or median (range) if not normally distributed. Continuous data were compared using Student’s t-test or Mann-Whitney U-test. Categorical variables were compared by Chi-square or Fisher’s exact test as appropriate. Additional Cox regression was also conducted to assess the freedom from AF/AT during follow-up. Variables of clinical importance or those with a significant intergroup difference at baseline will be included in the regression model. A P-value of 0.05 was considered statistically significant. Statistical analyses were performed using R 4.0.2.
