1 · What the graph read from 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.

2 · The registry

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

Peak width of skeletonized mean diffusivity (PSMD) is a reliable marker of white matter (WM) integrity in cerebral small vessel disease (CSVD). However, the mediating role of WM damage (as measured by PSMD) in the association between CSVD and cognitive impairment remains unclear. This research applied multivariate regression analysis to explore correlations among CSVD markers, PSMD and cognitive function in older community residents. Additionally, we analysed associations between PSMD and cognitive performance across different CSVD burden levels. Simple and chain mediation analyses were employed to evaluate PSMD's mediating role in the relationship among cerebrovascular risk factors, CSVD and cognitive decline. The cohort consisted of 273 participants categorized by CSVD severity into mild, moderate and severe groups. Each CSVD marker, along with PSMD, was significantly correlated with cognitive performance when controlling for demographic factors (age, sex and education) and apolipoprotein E (APOE) genotype. PSMD fully mediated the relationship between enlarged perivascular spaces and both the Mini-Mental State Examination and Modified Common Objects Sorting Test scores, while it partially mediated the relationships involving the CSVD burden, white matter hyperintensity volume, lacunes and cerebral microbleeds (indirect effect
