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

backgroundThe aim of this study was to evaluate atrial electromechanical delay (AEMD) with both electrocardiography (ECG) and echocardiography in patients with Chronic Obstructive Pulmonary Disease (COPD).

methodsTotal of 110 patients were included in this cross-sectional case-control study. P-wave dispersion (PWD) was measured on a 12-lead ECG. Atrial electromechanical intervals (PA) were measured as the time interval between the onset of the P wave on the ECG and the beginning of the late diastolic A wave.

resultsPWD was found to be 40.9±9.2 ms in the healthy control group, 45.6±8.2 ms in the mild COPD and 44.8±8.7 ms in the severe COPD group (p<0.05). Intra-right atrial EMD was found to be 10.7±5.8 ms in mild COPD, 11.0±7 ms in severe COPD, and it was 16.4±7.3 ms in healthy control group (p<0.001). Interatrial EMD was detected to be 29.5±9.1 ms in the control group, 24.1±9 ms in mild COPD group, and 23.9±11.1 ms in the severe COPD group (p<0.001).

conclusionBoth mild and severe COPD groups decreased PWD, increased tricuspid PA and significantly decreased interand right intra-AEMD times in comparison to the control group.
