Cardiac Magnetic Resonance Imaging in COVID-19 Vaccine-Associated Myocarditis Compared With Classical Myocarditis.
Article in JACC. Advances, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Studies comparing COVID-19 vaccine-associated and classical myocarditis (CM) are lacking. Objectives: The purpose of this study was to compare cardiac magnetic resonance (CMR) imaging findings and short-term clinical outcomes in patients with messenger RNA COVID-19 postvaccination myocarditis (PVM) and CM. Methods: This was a retrospective study of patients with myocarditis: 31 with PVM and 46 with CM. Patients underwent a CMR protocol scan including T1 and T2 sequences. Late gadolinium enhancement (LGE) was expressed as percentage of left ventricular myocardial mass and the extracellular volume was calculated based on precontrast and postcontrast T1 images. Clinical outcomes included heart failure hospitalizations and mortality. Results: Study patients were predominantly male (81% in PVM vs 89% in CM, Conclusions: Our study shows similar CMR imaging findings and short-term outcomes in PVM and CM, although PVM was associated with milder myocardial abnormalities and more frequent pericardial involvement.
