Clinical outcomes in recently diagnosed atrial fibrillation related to mitral stenosis compared to non-valvular atrial fibrillation.

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: Atrial fibrillation (AF) is the most common sustained arrhythmia in adults and is associated with significant morbidity and mortality. Mitral stenosis (MS) is common in developing countries, affecting the younger population and posing a risk of atrial fibrillation. Objectives: This study aims to delineate the clinical characteristics and poor outcomes in patients who have recent non-valvular AF (NVAF) compared with AF related to MS (MS-AF). Furthermore, it seeks to assess the healthcare resource utilization associated with the management of AF patients in the two groups. Patients and methods: This is a prospective observational cohort conducted on 84 patients with recent AF. The patients were divided into two groups: the NVAF group (patients with no prosthetic valves or moderate/severe MS) and the MS-AF group (patients with AF in the presence of moderate/severe MS). The clinical characteristics, stroke risk, and anticoagulation regimens were assessed. AF-related outcomes (strokes, hospitalizations, major bleeding, and mortalities) were monitored and compared between the two groups. Results: The mean age of the studied AF patients was 49.80 ± 16.31 years, ranging from 25 to 89 years. Patients with MS-AF were significantly younger than patients with NVAF. Hypertension was the most prevalent risk factor associated with AF. Smoking, heart failure, and hypertension were more prevalent among patients with NVAF. The NVAF group received less anticoagulants than the MS-AF group. There were no statistically significant differences between the two groups regarding the overall incidence of death, stroke, myocardial infarction, TIA, or hospital admissions. In the overall studied group, all-cause mortality was higher among AF patients with a history of heart failure or stroke. Conclusion: Patients with NVAF had a significantly greater incidence of cardiovascular disease risk factors. However, AF related to mitral stenosis was associated with comparable worse outcomes.
