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

Valvular and vascular calcifications are common among patients with end-stage renal disease, but diffuse calcification of the left ventricle is rarely reported. We report on a rare case of restrictive cardiomyopathy resulting from severe myocardial calcification and review the literature. A 77-year-old man was diagnosed with end-stage renal disease after having received regular haemodialysis for 20 years. He was referred to our emergency room due to exertional dyspnoea and exacerbated shortness of breath. A chest X-ray revealed severe pulmonary oedema and bilateral massive pleural effusion. Transthoracic echocardiography revealed impaired diastolic function of the left ventricle but preserved systolic function with a 50% ejection fraction. Repeat chest computed tomography demonstrated exacerbation of the calcification from the mitral annulus to the whole circular left ventricle. A coronary angiogram revealed non-significant stenosis, and right heart catheterisation demonstrated elevated pulmonary capillary wedge pressure. He was discharged after two weeks of conservative medication.
