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
introductionAtrial fibrillation (AF) is mainly triggered by arrhythmogenic foci originating from atrial myocardial extensions (MEs) into the pulmonary veins (PVs). Aim of the study was to evaluate endocardial voltage maps of PVs as a surrogate parameter for the extent of MEs in subjects with AF through a ultra-high-density mapping system.
methodsSixty-four bipolar electrograms were recorded simultaneously from the Orion mini-basket catheter placed in 72 PVs of 18 consecutive patients with paroxysmal/persistent AF undergoing PV isolation (PVI). The Rhythmia system in conjunction with the Orion mini-basket catheter was utilized to create a bipolar electro-anatomic reconstruction of the left atrium and PVs.
resultsMean patients' age was 61 ± 10 years, 56% had paroxysmal and 44% persistent AF. Mean endocardial bipolar voltages in the PVs were as follows: 1.06 ± 0.34 mV in right superior PV, 1.14 ± 0.52 mV in right inferior PV, 1.15 ± 0.44 mV in left superior PV and 0.94 ± 0.44 in left inferior PV. PVs had no detectable endocardial signals in 7 out of 72 PVs (9%); a total of 29/72 PVs (40%) revealed a non-uniform arrangement of MEs. The area of MEs was significantly larger in the superior PVs compared to the inferior PVs (9.3 ± 4.7 vs 6.7 ± 4 cm
conclusionIn this pilot study using a ultra-high-resolution electro-anatomical mapping system, endocardial voltage maps of PVs as a surrogate parameter of MEs among patients with AF well correspond to previous data from histopathological studies.
