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
purposeUnintended lesion formation on the left atrial (LA) posterior wall (LAPW) can occur during pulsed field ablation (PFA) for pulmonary vein (PV) isolation (PVI). We aimed to identify the factors associated with LAPW conduction block (LAPWB) during PVI using a pentaspline PFA catheter.
methodsWe retrospectively studied 99 consecutive patients undergoing an initial PVI of atrial fibrillation (AF) using the pentaspline catheter with basket and flower configurations at the PV ostium.
resultsPost-PVI mapping revealed LAPWB in 19 patients (19.2%). The ratio of the LAPW scar area was higher in the patients with LAPWB than those without (median, 70.5% vs. 41.0%, P < 0.001). The patients with LAPWB had a smaller LA volume (computed tomography [CT], 97.1 ± 24.1 vs. 122.9 ± 34.6 mL) and LAPW area (CT, 10.1 ± 2.7 vs. 14.3 ± 3.1 cm
conclusionsAF patients with smaller LA and LAPW sizes, especially a shorter inter-superior PV distance on the 3D-map (< 30.3 mm in this study), may be at an increased risk of unintended LAPWB during PVI using the pentaspline catheter with basket and flower configurations.
