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
introductionBachmann's bundle pacing (BBP) is associated with shorter p-wave duration (PWD) and reduced atrial fibrillation (AF) recurrence compared to right atrial appendage pacing (RAAP). We investigated the differences in acute left atrial pressure (LAP) measured invasively between sinus rhythm, BBP and RAAP. METHODS AND
resultsAcute LAP and PWD were measured in subjects undergoing left atrial catheter ablation in sinus rhythm, during BBP and RAAP at the end of ablation. Differences in PWD and LAP were determined by paired t-tests. Among 26 subjects (age 56.6 ± 14.2years, 27% female, 11% left-sided accessory pathway ablation, 54% pulmonary vein isolation[PVI], 35% PVI+additional LA ablation), BBP was successful in 24 subjects. Adjusted for age, only PWD was significantly associated with LAP in sinus rhythm (ß 0.12, p = 0.039). Compared to sinus rhythm and RAAP, BBP was associated with significantly shorter PWD (p < 0.05), but LAP was not significantly different (p > 0.05). In subgroup analyses, BBP remained associated with significantly shorter PWD, but was also associated with lower acute LAP compared to RAAP (16.7 ± 5.5 mmHg vs. 17.0 ± 6.0 mmHg, p = 0.010), among patients with interatrial conduction delay, defined as PWD>120 ms during sinus rhythm. Acute LAP was similar between BBP, sinus rhythm and RAAP in other subgroups (paroxysmal vs. persistent AF, PVI vs. PVI+additional LA ablation, left ventricular ejection fraction <50% vs. ≥50%; all p > 0.05).
conclusionReductions in PWD during BBP did not correspond with uniform reductions with acute LAP. Acute LAP was lower in BBP than RAAP, but its clinical significance in reducing AF requires further study.
