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

Our research presents a new animal model of transient ischemic attack (TIA) that mimics brief episodes without cell loss, but results in neuronal and behavioral deficits. We identified excessive microglial reactivity, driven by acute ATP release, as a key factor in post-TIA neurological deficits, which were ameliorated by inhibiting the P2Y12 receptor, a microglia-specific purinergic receptor in the brain parenchyma responsible for activity-dependent microglial cell-cell interactions. This finding suggests that modulation of microglial reactivity offers a promising strategy to prevent cognitive impairment in TIA patients, opening avenues for future research in this underexplored area.
