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).
