Utility of Routine 24-Hour Electrocardiographic Holter Monitoring for Detecting Atrial Fibrillation in Patients Admitted with Acute Stroke Syndromes.

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
Objectives: This study aimed to assess the operating characteristics of standard 12-lead electrocardiogram (ECG) and 24-hour Holter studies in detecting atrial tachyarrhythmia in patients with acute stroke syndromes. The study's objective was to determine the potential factors that increased the likelihood of detecting atrial fibrillation (AF) and its impact on management. Methods: This retrospective cohort study included adults (aged ≥18 years) admitted at Sultan Qaboos University Hospital from January 2010 to December 2019, with ischaemic stroke or transient ischaemic attack and had undergone a 24-hour Holter study. The hospital stroke registry was used to screen patients. Results: A total of 1,258 patients were screened and only 460 patients, who had undergone 521 Holter studies, met the inclusion criteria. Among them, AF was detected with baseline ECG in 20 patients (4.4%), while new AF was detected in only eight patients (1.7%). Significant predictors for increased AF detection by Holter included advanced age, peripheral vascular disease (PVD), left ventricular diastolic dysfunction and chronic kidney disease Stage III, with PVD highlighted as an independent predictor (odds ratio = 17.133, 95% confidence interval = 2.139-137.201, Conclusions: This study showed that a routine ECG Holter study in acute stroke has a low clinical yield in detecting AF, which is in substantial agreement with baseline ECG. Therefore, further investigation of paroxysmal AF in acute stroke should be reserved for high-risk patients.
