Hypothyroid heart: myxoedema as a cause of reversible dilated cardiomyopathy.
Article in BMJ case reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
Hypothyroidism may cause several cardiac manifestations including conduction abnormalities, pericardial effusion, decreased myocardial contractility and accelerated coronary atherosclerosis. Although cardiac output is reduced in hypothyroidism, frank heart failure (HF) is relatively rare because of the low peripheral oxygen demand. Several mechanisms have been postulated in hypothyroid-induced HF, including genomic as well as non-genomic actions of thyroid hormone. Dilated cardiomyopathy (DCM) of other aetiologies is usually progressive, and is associated with significant morbidity and mortality. We report a case of DCM associated with severe hypothyroidism with marked improvement on restoration of euthyroid state. Our case is unique in that the patient had no known risk factors for cardiac disease and experienced marked improvement despite being on minimal doses of HF medications, illustrating the relationship between hypothyroidism and development of left ventricular dysfunction, and its reversible nature with restoration of euthyroid status.
