The role of Tau, amyloid-β and neuroinflammation in the association between cognition and white matter hyperintensities in a southeast Asian cohort.

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
backgroundElevated Glial Fibrillary Acidic Protein (GFAP) is associated with increased Phosphorylated Tau 181 (pTau181) induced neurodegeneration in Alzheimer's Disease.
objectiveHowever, the role of GFAP and pTau181 in vascular/mixed dementias requires elucidation within the Southeast Asian context, where their burden is considerable.
designPopulation based cross-sectional study.
settingBiomarkers and Cognition Study, Singapore (BIOCIS).
participantsBaseline data from n = 583 (40.3 % male), non-demented but at risk, Southeast Asian community participants, were included in this analysis. All participants displayed cognitive symptoms on the Subjective Memory Complaints Questionnaire, although they may or may not have objective cognitive deficits and did not meet the criteria for dementia as per the DSM - 5.
methodsNeuropsychological assessments for executive function evaluation, volumetric White Matter Hyperintensities (WMH) measurement and plasma biomarker expression, were determined in non-demented but at risk, Southeast Asian research participants. Partial correlation analysis demonstrated variable associations. Simple moderation analysis revealed the ability for plasma biomarkers to influence the relationship between executive function and WMH.
resultsWMH burden positively correlated to Neurofilament-Light (NfL) and pTau181. Executive function and processing speed negatively correlated to WMH burden. GFAP positively correlated to pTau181 and negatively correlated to executive function. NfL, GFAP, pTau181, and Amyloid beta 42/Amyloid beta 40 (Aβ42/Aβ40) ratio independently moderated, the relationship between executive function/processing speed and WMH burden.
conclusionInflammatory mechanisms represented by GFAP were linked to tau pathology and WMH and also moderated the association between WMH on cognitive performance.
