Amphetamine-Associated Reversible Biventricular Cardiomyopathy Complicated by Acute Respiratory Failure: A Case Report.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Amphetamine overdose can cause severe cardiovascular toxicity, including rarely reversible cardiomyopathy. A 26-year-old man presented approximately 33 hours after intentionally ingesting 25 20-mg extended-release mixed amphetamine salt tablets with lorazepam. He developed chest pain, tachycardia, hypotension, hypoxemia, lactic acidosis, rhabdomyolysis, and markedly elevated cardiac biomarkers. Electrocardiography showed diffuse ST-segment depressions, and chest imaging demonstrated bilateral pulmonary edema and acute lung injury without pulmonary embolism. Echocardiography revealed severe global biventricular systolic dysfunction with a left ventricular ejection fraction below 20%. Progressive hypoxemic respiratory failure required intubation and mechanical ventilation. He improved with supportive intensive care, intravenous diuresis, and heart failure therapy. Although coronary angiography was recommended, he declined and left against medical advice. At two-month follow-up, echocardiography showed complete recovery of biventricular function, with an ejection fraction of 55-60%. This case highlights profound but reversible biventricular cardiomyopathy following massive extended-release amphetamine overdose.
