Significance and Usefulness of High-Resolution 24-h Electrocardiographic Parameters in Patients With Coronavirus Disease 2019 After Admission: A Prospective Cohort Study.

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: This study aimed to explore the predictors of disease severity in patients with coronavirus disease 2019 (COVID-19) using ambulatory electrocardiographic markers (AECG-Ms), which are prognostic predictors of cardiac death, as well as echocardiography and laboratory parameters. Methods: A prospective cohort study was conducted using data from 70 patients diagnosed with COVID-19 and admitted to the National Defense Medical College Hospital between January 2021 and December 2023. A high-resolution Holter electrocardiogram recorder was attached to all patients for 24 h within 48 h of admission, and AECG-Ms were measured. Laboratory tests and echocardiography were also performed. Results: Logistic univariate analysis revealed that the T-wave alternans (TWA) positivity rate was significantly higher in the fatal event group (all-cause mortality and onset of sustained ventricular tachycardia or ventricular fibrillation) than in the non-fatal event group. Kaplan-Meier curves at 30 days after admission showed a significant worsening in the survival rate of the TWA and late potential positive groups (log-rank test, Conclusion: In patients with COVID-19 without obvious cardiac disease, AECG-Ms were highly positive. The study findings may allow easy and rapid prediction of prognosis at the bedside of patients with COVID-19.
