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).
