OCTA-Derived Retinal Biomarkers and Infarct Topography Improve Etiologic Classification of Recent Single Subcortical Infarction: A Nomogram Model.
Article in CNS neuroscience & therapeutics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundRecent single subcortical infarction (RSSI) in lenticulostriate artery territories exhibits etiological heterogeneity. Misclassification risks persist due to overlapping neuroimaging features between cerebral small-vessel disease-related lacunar infarction (CSVD-related LI) and branch atheromatous disease (BAD). We developed a nomogram that integrates retinal optical coherence tomography angiography (OCTA) metrics with infarct topography to improve etiological classification.
methodsPatients with RSSI were prospectively enrolled between December 2021 and December 2023. LASSO regression identified predictors for a logistic regression-based nomogram. Performance was evaluated via concordance index (C-index), calibration curves, and decision-curve analysis.
resultsA total of 127 RSSI patients (86 CSVD-related LI, 41 BAD) were included. Three variables-superficial vascular complex density, number of lesion slices, and proximal lesion location-were retained in the final model. The nomogram achieved a C-index of 0.84 (95% CI, 0.80-0.89) versus 0.68 for conventional imaging, with superior net benefit across clinical thresholds (AUC 0.84 vs. 0.68, p < 0.001).
conclusionThe novel nomogram combining OCTA-derived retinal biomarkers with infarct topography improves differentiation of BAD from CSVD-related LI in RSSI patients and may facilitate etiology-driven clinical decision-making. External validation is needed for clinical implementation.
