Cognitive Compensation Depends on Frontoparietal Network Structure-Function Coupling in Patients With White Matter Hyperintensity.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 purposeWhite matter hyperintensity (WMH) impairs cognitive function but is not evident in the early stage, raising the need to explore the underlying mechanism. We aimed to investigate the potential role of network structure-function coupling (SC-FC coupling) in cognitive performance of WMH patients.
methodsA total of 617 participants with WMH (mean age = 61 [SD = 8]; 287 females [46.5%]) were retrospectively included from the Cognitive Impairment, Retinopathy, and Cerebrovascular Lesions in the Elderly (CIRCLE) study who underwent multimodal MRI and comprehensive cognitive assessments. Severe WMH was defined as periventricular WMH with a Fazekas score of 3 and/or deep WMH with Fazekas score ≥ 2; otherwise it was defined as mild WMH. The network SC-FC coupling was derived from diffusion tensor imaging and functional MRI.
resultsAcross networks, the frontoparietal network exhibited the lowest SC-FC coupling, while the somatomotor network was the highest. Within the mild WMH subgroup, only frontoparietal network SC-FC coupling was positively correlated with WMH volume (β = 0.136, p = 0.014), a pattern not observed in the whole cohort and the severe WMH subgroup (all p > 0.05). Furthermore, in the mild WMH subgroup, frontoparietal network SC-FC coupling was also positively correlated with cognitive performance on the digit span forward task, both in cross-sectional (β = 0.110, p = 0.023) and longitudinal analyses (β = 0.245, p = 0.038).
conclusionsOverall, the frontoparietal network SC-FC coupling may contribute to cognitive compensation during the mild stage of WMH and could be a target for interventions aimed at preserving cognitive abilities.
