Patient characteristics and procedure details in the PSM cohort:
After PSM there were 275 patients in each group. Covariates were well balanced between the two groups. Characteristics of the two groups are presented in Table 2. Mean age was 64 years and mean BMI 30. 85% of the patients had paroxysmal AF. After propensity matching for risk factors, the colchicine group had more additional ablations other than PVI (OR 3.67, 95% CI [2.55, 5.32], P<0.001).
