Early Prediction of Paroxysmal Atrial Fibrillation in Patients With Acute Stroke Using the BANQMR Score.
Article in Journal of clinical neurology (Seoul, Korea), 2025. 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 and purposeParoxysmal atrial fibrillation (PAF) can cause embolic stroke but is often asymptomatic and may resolve before it can be detected. We developed a simple, practical scoring system to improve the detection of PAF in stroke patients.
methodsPatients with acute ischemic stroke hospitalized in three stroke centers between 2014 and 2021 were retrospectively examined. Multivariate logistic regression analysis was used to identify independent risk factors for PAF in a derivation cohort. Using these factors, a scoring system was developed and validated in a separate cohort.
resultsThe derivation and validation cohorts included 649 and 583 patients, respectively. Median follow-up was 606 and 101 days, respectively. The independent risk factors for PAF were brain natriuretic peptide (BNP) ≥55 pg/mL, atrial premature contractions (APCs), National Institutes of Health Stroke Scale (NIHSS) score ≥11, corrected QT interval (QTc) ≥0.46 seconds, and multiple acute cerebral infarcts (MACIs). The BANQMR score assigns points based on these factors (BNP=3, APC=3, NIHSS score=2, QTc=1, and MACIs=1) and classifies patients into three risk grades based on points: low (0-2), moderate (3-5), and high (6-10). PAF was actually detected in 53.4% of high-risk patients, 15.0% of moderate-risk patients, and 4.6% of low-risk patients. The BANQMR score outperformed other existing scoring systems in terms of PAF prediction.
conclusionsThe BANQMR score is a simple, accurate tool for predicting PAF in ischemic stroke patients shortly after hospitalization, providing a clinically applicable method for early detection.
