Appropriateness of oral anticoagulant therapy and associated factors among hospitalized atrial fibrillation patients with the CHA
Article in eNeurologicalSci, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 cardiac rhythm disturbances associated with increased risks of mortality. Oral anticoagulant (OAC) reduces AF-related strokes. However, the pattern of OAC use among AF patients is unknown in Ethiopia. This study evaluated the appropriateness of OAC therapy and associated factors among hospitalized AF patients. Methods: A retrospective cross-sectional study was conducted among AF patients hospitalized in medical ward of Adigrat general hospital. Previously validated CHA Results: Of the total 84 AF patients, more than half (52.4%) were females and their median age was 64.50 (75-39.5). About 42.9 and 31.0% of the patients were at high risks of stroke and bleeding, respectively. Thirty seven (44.0%) of the patients received no antithrombotics and almost half (48.8%) of them were not prescribed OAC. On the other hand, 51.2% of patients received OAC containing regimen, 40.5% were prescribed with OAC monotherapy and 4.8% received aspirin monotherapy. Among patients at high risk of stroke, 36.1% of them received no antithrombotic drug. Regarding risk of bleeding, the prescription of OAC containing regimen among patients at high risk of bleeding was lower than in those at low risk of bleeding (41.9% versus 56.6%). Almost two third (61.9%) of AF patients were prescribed inappropriately, dominantly being underprescribed (44.0%). Admission time for AF was significantly associated ( Conclusions: Substantial proportions of AF patients at high risk of stroke were inappropriately prescribed with OACs. Inappropriate prescription was characterized by underprescription. The cardiologists of the hospital should follow AF guidelines to improve prescription patterns with an ultimate goal of improving treatment outcomes.
