The Predictive Value of Circulating Gal-3 for New Stroke Events in Paroxysmal Atrial Fibrillation Patients Despite Oral Anticoagulation Medications.
Article in Clinical cardiology, 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
backgroundCHA2DS2-VASc is used to assess the risk of stroke in patients with atrial fibrillation (AF) and guide anticoagulant treatment decisions, but it has limitations in accurately predicting stroke risk in individual patients. The objective of this study is to conduct a cohort study by assessing preoperative levels of Gal-3 in paroxysmal AF patients, aiming to observe its correlation with the subsequent incidence of stroke events.
methodThis study enrolled 197 patients with nonvalvular paroxysmal AF. Blood samples were taken to test Gal-3 levels. All patients were followed up for 4 years after admission.
resultsCompared to the nonstroke cases, serum levels of Gal-3 were markedly elevated in stroke cases (7.08 [IQR, 4.60-10.96] vs. 17.34 [IQR, 8.28-20.31], p < 0.001). Gal-3 yields a superior AUC (0.748, with a 95%CI of 0.681-0.807) compared to other classical stroke indices, such as BNP, CHA2DS2-Vas score, and TNI. Remarkably, the Gal-3 index exhibited a superior predictive capacity, yielding a significant incremental predictive value that surpassed the conventional risk factors (CHA2DS2-VASc score) for stroke events, as evidenced by an IDI of 16.4% (p < 0.001) and an NRI of 34.7% (p = 0.002).
conclusionThe presence of Gal-3 is an independent risk factor for stroke in patients with AF. Elevated levels of Gal-3 have the potential to serve as a valuable biomarker for identifying incident strokes in AF patients. Furthermore, incorporating the assessment of Gal-3 levels into the conventional CHA2DS2-VASc score could significantly enhance its predictive accuracy for stroke in AF patients.
