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

introductionChronic neuroinflammation in Alzheimer's disease (AD) alters astrocyte physiology and neurovascular unit function. AD patients frequently experience recurrent systemic inflammatory insults from comorbid conditions, which act as "secondary-hits" believed to worsen cognitive decline. The impact of these secondary insults  on astrocyte-mediated neurovascular regulation remains unknown.

methodsWe applied intravital two-photon microscopy to longitudinally investigate astrocytic Ca

resultsAD mice exhibited diminished stimulation-evoked astrocytic Ca DISCUSSION: Our findings provide the first in vivo longitudinal characterization of how secondary systemic inflammation disrupts astrocyte-mediated neurovascular regulation. The selective vulnerability of astrocytic Ca
