Evaluation of predictors indicating paroxysmal atrial fibrillation in patients with acute ischemic strokes: the Find-AF
Article in Neurological research and practice, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01855035 (A Prospective, Randomised, Controlled Study to Determine the Detection of Atrial Fibrillation by Prolonged and Enhanced Holter Monitoring as Compared to Usual Care in Stroke Patients), which is not on this 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.

Abstract
backgroundDetecting concealed paroxysmal atrial fibrillation after stroke requires elaborate electrocardiographic monitoring. We evaluated previously established predictors to quantify the individual risk of detecting atrial fibrillation within six months in the Find-AFRANDOMISED-trial.
methodsWe analyzed 200 patients ≥ 60 years with acute ischemic strokes in the intervention arm of the Find-AFRANDOMISED-trial. Patients received three ten-day Holter-electrocardiograms within six months. Regression analyses and receiver-operator-characteristics were used to select promising biomarkers and assess predictive performance. We applied previously established cut-offs for the most promising markers to determine those at a high risk of underlying atrial fibrillation.
results27/200 patients (13.5%) had atrial fibrillation after six months. The left atrial diameter, atrial premature beats, supraventricular runs and brain natriuretic peptide were associated with atrial fibrillation, whereas the established markers age and suspected stroke etiology were not. Atrial premature beats differentiated best between those with and without atrial fibrillation (area-under-the-curve = 0.75). Only brain natriuretic peptide ≥ 100pg/ml and supraventricular runs ≥ 20 beats independently predicted atrial fibrillation in multivariable models.
conclusionsSupraventricular runs and brain natriuretic peptide were the most promising predictors to define a high risk of underlying atrial fibrillation after stroke in our study. Future screening strategies for atrial fibrillation in stroke patients should focus on these parameters rather than the suspected stroke etiology.
