Accuracy of Apple Watch in Measuring 30-Second Resting Electrocardiography in Patients with Cardiac Diseases and Comorbidity: An Observational Cross-Sectional Study.
Article in Journal of multidisciplinary healthcare, 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
Background: Electrocardiography (ECG) is a standard method for studying the heart rate and heart electricity. The Apple Watch has recently been used to measure heart electricity via 30 seconds of ECG monitoring, but its validity is not known. Methods: A cross-sectional study included a sample of 112 patients with chronic disorders, including cardiac patients with sinus rhythm, cardiac patients with irregular heart rhythm, and patients with diabetes, hypertension, and dyslipidemia; their cardiac activity was investigated using the Apple Watch and ECG. Results: The correlations were strong between the Apple Watch and the 12-lead ECG in the heart rate, PR intervals, QT intervals, QRS complex, and RR intervals in all patients' subcategories (cardiac, hypertension, diabetic, and dyslipidemia patients). Conclusion: The Apple Watch is valid for carrying out ECG in measuring the heart rate, PR intervals, QT intervals, QRS complex, and RR intervals of patients with cardiac and chronic diseases at rest; this may help in initial diagnosis for patients with cardiac diseases or those who are at risk of developing cardiac disease in the future.
