New clinical application of magnetocardiography: diagnosis of left ventricular hypertrophy.
Article in Frontiers in cardiovascular medicine, 2025. 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
Introduction: Magnetocardiography (MCG), as a high-sensitivity, non-contact and non-invasive technology, is assumed to detect weak electrophysiological changes. MCG can detect early signs of myocardial ischemia that may be missed by other diagnostic tools. Present research aims to evaluate the possibility of using MCG to detect left ventricular hypertrophy (LVH). Methods: The study included 481 participants, categorized into two groups according to echocardiographic criteria: the LVH group and the non-LVH group. We evaluated the performance of the MCG-derived diagnostic model for detecting LVH in the retrospective cohort and performed external validation in the prospective cohort. Using echocardiography as the reference standard, we assessed the model's area under the curve (AUC) value, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy. Results: MCG parameters (S Conclusion: Besides myocardial ischemia, MCG also provides useful information suggestive of LVH.
