Loeys-Dietz syndrome and isolated severe ostial left main coronary stenosis presenting as ventricular fibrillation arrest and biventricular takotsubo syndrome in a 25-year-old patient.
Article in BMJ case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
We present the case of a previously healthy 25-year-old woman who presented with an out-of-hospital ventricular fibrillation arrest. Postresuscitation ECG did not show any evidence of ST segment elevation. Echocardiogram showed regional wall abnormalities in keeping with takotsubo syndrome (TTS). Urgent coronary angiogram to rule out malignant congenital coronary artery anomaly revealed an isolated severe ostial left main coronary artery (LMCA) stenosis, a rare disease, approximately 0.2% in previous case series. The LMCA was aneurysmal. Genetic studies revealed a novel frameshift pathogenic variant in the transforming growth factor B two ligand gene (TGFB2) gene, suggestive of Loeys-Dietz syndrome (LDS) type 4, an aggressive vascular disease. Ostial LMCA stenosis has not been previously reported in LDS, and we outline the management of this unique disease combination. We also reflect on its presentation as TTS and infer that TTS and acute coronary syndromes are not mutually exclusive.
