Statistical analysis
Continuous data are expressed as means ± standard deviations or as
medians with interquartile ranges. Categorical data are presented as
absolute values and percentages. Continuous variables were compared
using the t-test or Mann–Whitney U test if applicable, and
dichotomous variables were compared using the chi-square test or
Fisher’s exact test. A P- value of <0.05 was considered
statistically significant. Univariate and multivariate logistic
regression analyses were performed to determine the clinical factors
associated with AF recurrence. Parameters with P -values
<0.20 were included in the multivariate logistic regression
analysis performed to assess the independent predictors of AF
recurrence. All analyses were performed using JMP 14 software (SAS
Institute, Cary, NC, USA).
