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

Background: Vascular cognitive impairment (VCI) is a prevalent form of cognitive dysfunction. Resting-state functional magnetic resonance imaging (rs-fMRI) could serve as a potential biomarker for early detection. This study employed activation likelihood estimation (ALE) meta-analysis to investigate specific neural abnormalities in VCI patients. Methods: We systematically searched PubMed, Embase, and Web of Science for rs-fMRI studies on VCI that reported amplitude of low-frequency fluctuation (ALFF), regional homogeneity (ReHo), or functional connectivity (FC). Sixteen eligible fMRI studies were included in the ALE meta-analysis. Results: Compared to healthy controls (HCs), VCI patients exhibited the following rs-fMRI alterations. For ALFF, there was an increase in the left anterior cingulate (AC) and left inferior frontal gyrus, possibly a compensatory over - activation. Decreases were seen in regions like the bilateral precuneus and medial frontal gyri (mFG), linked to cognitive deficits. ReHo increased in the left claustrum and insula, suggesting enhanced local synchronization, but decreased in the right sub - gyral region and middle temporal gyru (MTG), which may relate to language issues. FC was enhanced in areas related to complex cognitive processes, yet reduced in regions crucial for memory. Conclusion: VCI patients exhibited distinct functional abnormalities in specific brain regions, reflecting their diverse cognitive impairments. These region-specific alterations may serve as potential biomarkers for early diagnosis and targeted intervention in VCI.
