Based on procedure start time, patients were assigned to a daytime group (08:00\u201316:00,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20091503) or a nighttime group (16:00\u201324:00,\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20091301). Propensity score matching (PSM) was used to balance baseline characteristics. The primary outcome was any complication within 3 months post\u2011ablation.
