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

Background: In patients with apical hypertrophic cardiomyopathy (HCM), electrocardiography (ECG) often shows left ventricular hypertrophy (LVH) and a negative T wave. A negative T wave often disappears over time due to degeneration of the apical myocardium. However, there are limited reports on the temporary change of a negative T wave in patients with HCM. Case summary: We report three apical HCM patients with LVH and T wave inversion on their previous ECG who showed a temporary decrease in the depth of the negative T wave. All of them had significant stenosis of coronary arteries including the left anterior descending artery (LAD). After revascularization for the LAD lesion, their ECG returned to the previous depth of the negative T wave. Discussion: The cases presented here suggested that a temporary decrease in the depth of the negative T wave in apical HCM patients may be one of the signs of ischaemia in the anterior-apical region caused by severe stenosis of the LAD.
