AF recurrence and no-recurrence at 12-months of follow-up (absolute number of patients) by center experience. Centers were divided into four quartiles of expertise with a fixed range of 55 patients in each quartile, increasing in the level of experience. There was not statistical difference regarding either overall recurrence at 12-month follow-up or the rate of adverse events. Procedure characteristics were different between quartiles (Table S2).
