Correlating Left Atrial Enlargement and Left Ventricular Hypertrophy on ECG With Echocardiography and Cardiac Magnetic Resonance Imaging.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundECGs are a primary assessment of cardiac structure and function. Alignment of their findings with cardiac imaging is not well defined. This study investigates the correlation of left atrial enlargement and left ventricular hypertrophy (LVH) found on ECG with transthoracic echocardiogram and cardiac magnetic resonance imaging (CMR) findings.
methodsThis is a single-center retrospective study of 1000 patients. It included patients with positive ECG criteria for left atrial enlargement or left ventricular hypertrophy (LVH) with transthoracic echocardiograms done within the same month. CMR data were included if within 6 months of the ECG. Receiver operator curves and area under the curves (AUC) were calculated based on whether ECG findings were confirmed on either imaging.
resultsLeft atrial enlargement ECG criteria best correlating with transthoracic echocardiograms were p-wave duration of 120+ ms in lead II (AUC, 0.81 [95% CI, 0.79-0.83];
conclusionsECG criteria for left atrial enlargement and LVH correlated poorly with both transthoracic echocardiograms and CMR. Updating current waveform criteria may improve diagnostic accuracy of ECGs.
