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

Chemokine C‑X3‑C motif ligand 1 (CX3CL1) and its sole receptor, CX3CR1, are known to be involved in neuronal damage/death following brain ischemia. In the present study, time‑dependent expression changes of CX3CL1 and CX3CR1 proteins were investigated in the hippocampal CA1 field following 5 min of transient global cerebral ischemia (tgCI) in gerbils. To induce tgCI in gerbils, bilateral common carotid arteries were occluded for 5 min using aneurysm clips. Expression changes of CX3CL1 and CX3CR1 proteins were assessed at 1, 2 and 5 days after tgCI using western blotting and immunohistochemistry. CX3CL1 immunoreactivity was strong in the CA1 pyramidal cells of animals in the sham operation group. Weak CX3CL1 immunoreactivity was detected at 6 h after tgCI, recovered at 1 day after tgCI and disappeared from 5 days after tgCI. CX3CR1 immunoreactivity was very weak in CA1 pyramidal cells of the sham animals. CX3CR1 immunoreactivity in CA1 pyramidal cells was significantly increased at 1 days after tgCI and gradually decreased thereafter. On the other hand, CX3CR1 immunoreactivity was significantly increased in microglia from 5 days after tgCI. These results showed that CX3CL1 and CX3CR1 protein expression levels in pyramidal cells and microglia in the hippocampal CA1 field following tgCI were changed, indicating that tgCI‑induced expression changes of CX3CL1 and CX3CR1 proteins might be closely associated with tgCI‑induced delayed neuronal death and microglial activation.
