Photon-counting CT of midventricular takotsubo cardiomyopathy.
Article in Radiology case reports, 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
Midventricular Takotsubo cardiomyopathy is an atypical variant of stress-induced cardiomyopathy characterized by circumferential midventricular hypokinesia with basal and apical sparing. We present the case of a 63-year-old woman presenting with acute chest pain and elevated cardiac troponin I following emotional stress. While echocardiography initially suggested apical involvement, Photon-Counting Detector Coronary CT Angiography (PCD-CCTA) provided a comprehensive "1-stop-shop'' assessment. The high-resolution photon-counting acquisition excluded obstructive coronary artery disease, while multiphase cine reconstructions definitively characterized the midventricular wall-motion abnormalities. Diagnosis was confirmed by the complete resolution of wall-motion abnormalities on follow-up cardiac MRI. This case highlights the capability of emerging photon-counting CT technology to simultaneously assess coronary anatomy and ventricular function, facilitating the rapid diagnosis of atypical cardiomyopathy variants.
