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

Idiopathic restrictive cardiomyopathy (RCM) is rare, and its natural history is not well known. Its prognosis in infants is extremely poor, whereas patients with RCM occurring in middle age have comparatively good prognoses. Here, we report a case of idiopathic RCM with the disease onset at 10 years old. Echocardiography and cardiac catheterization revealed a biventricular restrictive pattern; however, the right ventricle showed more severe restriction. At 20 years old, severe pulmonary thromboembolism (PTE) occurred with circulatory collapse. The right atrium was extremely enlarged and the appendage was filled with moderate thrombi that migrated to pulmonary arteries. PTE is a rare complication of idiopathic RCM; however, this complication occurs more commonly in other secondary RCMs. In patients with restrictive hemodynamic pattern, the presence of thrombi in cardiac cavities should be routinely examined.
