A Case of Infiltrative Cardiomyopathy Secondary to Primary Hyperoxaluria Type 2 - Utilization of Multimodality Imaging.
Article in Cureus, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Primary hyperoxaluria is a rare genetic disorder characterized by oxalate crystal deposition, including in the heart. Hyperoxaluria-associated cardiomyopathy manifests as restrictive infiltrative cardiomyopathy. We present a case of a 52-year-old male with a past medical history of type 2 primary hyperoxaluria, end-stage renal disease on hemodialysis, paroxysmal atrial fibrillation, and hypertension, who presented with dyspnea and lethargy. Transthoracic echocardiogram showed cardiomyopathy with ejection fraction (EF) of 35-40% with severe hypokinesis of apical myocardium. Endomyocardial biopsy revealed interstitial fibrosis and crystal deposition consistent with oxalate. Cardiac MRI showed late gadolinium enhancement with subendocardial, nearly transmural fibrosis of lateral wall along with mid myocardial involvement of anterior and septal wall. To the best of our knowledge, this is the first case of type 2 primary hyperoxaluria-associated cardiomyopathy utilizing transthoracic echo, endomyocardial biopsy, and cardiac MRI.
