a–d, Kaplan–Meier estimates of freedom from the secondary endpoints, which are freedom from any documented atrial arrhythmia more than 30 s after a single procedure, or up to two procedures, with or without the use of antiarrhythmic medications after a 3-month blanking period. Comparisons of the tailored arm versus anatomical arm were performed using the two-sided log-rank test. a, Outcome after a single procedure for all patients in the PP population (HR, 0.81; 95% CI, 0.56–1.19). b, Outcome after one or two procedures for all patients in the PP population (HR, 0.62; 95% CI, 0.38–1.01). c, Outcome after a single procedure for patients with a duration of AF greater or equal to 6 months in the PP population (HR, 0.60; 95% CI, 0.37–0.97). d, Outcome after one or two procedures for patients with a duration of AF greater or equal to 6 months in the PP population (HR, 0.50; 95% CI, 0.28–0.90).
