1 · What the graph read from it

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.

2 · The registry

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

Influence of left atrial wall thickness on outcome of catheter ablation for atrial fibrillation (AF) is unclear. Overall, 213 patients with AF (128 paroxysmal and 85 persistent) received ablation. We measured the wall thickness of 16 and 19 areas in the pulmonary vein antrum (PVWT) and left atrial body (LAWT), respectively. Coefficient of variation of wall thickness (CV-WT) was calculated to assess heterogeneity in the left atrial wall thickness. In patients with paroxysmal AF, maximum PVWT, mean PVWT, maximum LAWT, and CV-WT were higher in AF recurrent group than in AF-free group (maximum PVWT, 2.85 ± 0.52 vs. 2.50 ± 0.45 mm, P = 0.003; mean PVWT, 1.59 ± 0.13 vs. 1.50 ± 0.15 mm, P = 0.018; maximum LAWT, 3.85 ± 0.77 vs. 3.41 ± 0.61 mm, P = 0.005; CV-WT, 0.34 ± 0.06 vs. 0.32 ± 0.05, P = 0.039). In patients with persistent AF, maximum PVWT, mean PVWT, maximum LAWT, mean LAWT, and CV-WT were higher in the AF-recurrent group than in the AF-free group (maximum PVWT, 2.52 ± 0.36 vs. 2.31 ± 0.36 mm, P = 0.031; mean PVWT, 1.53 ± 0.12 vs. 1.45 ± 0.14 mm, P = 0.036; maximum LAWT, 3.68 ± 0.75 vs. 3.11 ± 0.50 mm, P < 0.001; mean LAWT, 2.34 ± 0.35 vs. 2.13 ± 0.21 mm, P = 0.002; CV-WT, 0.35 ± 0.06 vs. 0.31 ± 0.05, P = 0.005). Thick and heterogeneous left atrial wall contributes to AF recurrence after ablation.
