Propensity‐score matching for the total cohort (n=1568, 408 in ablated group, and 1160 in the nonablated group). A, Dot plot of patients in either matched or unmatched groups. B, Line plot of standardized differences before and after matching. C, Dot plot of standardized mean differences (Cohen's d) for all covariates before and after matching. D, Distribution of propensity scores of ablated (“treated”) and nonablated patients (“control”) before and after matching with overlaid kernel density estimate. E, Histograms with overlaid kernel density estimates of standardized differences before and after matching.
