Clinical, Imaging, and Atrial Cardiopathy Markers in Ischemic Stroke Subtypes - Clues to a Cardioembolic Source.

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
objectivesCryptogenic strokes account for 20%-25% of all ischemic strokes. Although atrial cardiopathy markers are more prevalent in the cryptogenic embolic stroke of undetermined source (ESUS) subgroup than in the nonembolic stroke subgroup, the utility of individual parameters in predicting cardioembolic sources needs to be studied further. We studied the clinical, imaging, and atrial cardiopathy markers in three ischemic stroke subtypes - large artery atherosclerosis (LAA), cardioembolism (CE), and cryptogenic ESUS - and their role in predicting the source of CE.
methodsThis was a prospective observational study of ischemic stroke patients at Department of Neurology, Sree Chitra Tirunal Institute for Medical Sciences and Technology, Trivandrum from April 2021 to December 2022. Clinical and risk factor profiles, imaging details, atrial cardiopathy marker (N-terminal pro-brain natriuretic peptide [NT-pro-BNP]) levels, electrocardiogram (ECG) parameters (P terminal force of V1 [PTFV1], P wave duration, the PR interval), and transthoracic echo parameters (left atrial [LA] diameter and LA volume) were collected. Associations were made between clinical, imaging, and atrial cardiopathy markers and etiological subtypes.
resultsWe had 255 participants (LAA- 98, CE- 41, and ESUS- 139) with a mean age of 63.53 years. Among the atrial cardiopathy markers, the most prevalent was elevated NT-pro-BNP (43.95%), followed by the ECG markers P wave duration (30.92%) and PTFV1 (28.74%), and LA diameter greater than 37 mm (24.27%) and LA volume greater than 34 ml/m 2 (20.31%). Among the atrial cardiopathy markers, NT-pro-BNP and LA enlargement were strongly predictive of CE etiology, when compared to LAA. Chronic non-lacunar infarcts on imaging and elevated NT-pro-BNP showed a strong association with CE, when compared to cryptogenic strokes.
conclusionsThe atrial cardiopathy biomarker NT-pro-BNP and chronic non-lacunar infarcts can serve as useful tools for recognizing cardioembolic sources among patients with embolic strokes.
