The study was powered to address the primary hypothesis that commencing with a left‐sided approach is more effective (RF ablation time) than a right‐sided approach. Souza et al.In February 2022, the independent DSMC reviewed and performed an interim analysis after 31 patients had been enrolled. On the basis of these interim results, the sample size was recalculated. Assuming a standard deviation of 155 seconds and 90% power, 3048 patients would have been required to detect a significant difference between the groups. Thus, on the basis of futility analysis, the independent DSMC recommended that enrollment be terminated.Continuous variables are presented as mean ± SD or median (interquartile range), as appropriate. Categorical variables are presented as absolute numbers and percentages. Continuous variables between groups were analyzed using Student The analyses were performed with the use of SPSS software, version 23.0 (SPSS, Inc.).
