Synthetic generation of cardiac tissue motion from surface electrocardiograms.
Article in Nature cardiovascular research, 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
Cardiac tissue motion is a sensitive biomarker for detecting early myocardial damage. Here, we show the similarity, interpretability and diagnostic accuracy of synthetic tissue Doppler imaging (TDI) waveforms generated from surface electrocardiograms (ECGs). Prospectively collected ECG and TDI data were cross-matched as 9,144 lateral and 8,722 septal TDI-ECG pairs (463 patients) for generating synthetic TDI across every 1% interval of the cardiac cycle. External validation using 816 lateral and 869 septal TDI-ECG pairs (314 patients) demonstrated strong correlation (repeated-measures r = 0.90, P < 0.0001), cosine similarity (0.89, P < 0.0001) and no differences during a randomized visual Turing test. Synthetic TDI correlated with clinical parameters (585 patients) and detected diastolic and systolic dysfunction with an area under the curve of 0.80 and 0.81, respectively. Furthermore, synthetic TDI systolic and early diastolic measurements generated from an external ECG dataset (233,647 patients) were associated with all-cause mortality during both sinus rhythm and atrial fibrillation, underscoring their potential for personalized cardiac care.
