Safety and Efficacy of Nighttime Versus Daytime Radiofrequency Catheter Ablation for Atrial Fibrillation: A Multicenter Cohort Study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to compare the incidence of post‑procedural complications in patients undergoing radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) performed during daytime versus nighttime hours.
methodsThis retrospective study included 2951 patients who underwent AF ablation at three centers between 2019 and 2024. Based on procedure start time, patients were assigned to a daytime group (08:00-16:00, n = 1503) or a nighttime group (16:00-24:00, n = 1301). Propensity score matching (PSM) was used to balance baseline characteristics. The primary outcome was any complication within 3 months post‑ablation. Secondary outcomes included in‑hospital and post‑discharge complications (within 3 months) and freedom from atrial arrhythmia recurrence at 12 months.
resultsFollowing 1:1 PSM, 1263 matched pairs were analyzed. The overall postoperative complication rate was significantly higher in the nighttime group than in the daytime group (4.99% vs. 2.30%; odds ratio [OR]: 2.23; 95% confidence interval [CI]: 1.43-3.49; p < 0.001). This elevated risk was consistent for both in-hospital complications (OR: 2.14; 95% CI: 1.23-3.72; p = 0.007) and post-discharge complications (OR: 2.32; 95% CI: 1.10-4.90; p = 0.027). Furthermore, there was no significant difference in the 12-month freedom from atrial arrhythmia recurrence between the two cohorts.
conclusionsNighttime AF ablation is associated with a significantly increased risk of overall postoperative complications, highlighting procedural timing as a critical determinant of perioperative patient safety.
