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

purposeThe purpose of this study was to test whether the fractional change in the endocardial border length between end-diastole and end-systole as manually traced in left ventricular ejection fraction (LVEF) measurement using the biplane method of disks (MOD) was consistent with the global longitudinal strain derived from speckle-tracking echocardiography.

methodsFor 105 patients who underwent echocardiography, two- and four-chamber images with manually traced endocardial lines for LVEF measurement by MOD were stored. LV endocardial lengths at end-diastole and at end-systole were measured on both images to calculate the fractional length changes, which were averaged (GLS

resultsThere was no significant difference between GLS
