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

Early brain injury (EBI) is a major cause of mortality from subarachnoid hemorrhage (SAH). We aimed to study the pathophysiology of EBI and explore the role of hepcidin, a protein involved in iron homeostatic regulation, and its downstream proteins. One hundred and thirty-two male Sprague-Dawley rats were assigned into groups (n = 24/group): sham, SAH, SAH + hepcidin, SAH + hepcidin-targeting small interfering ribonucleic acid (siRNA), and SAH + scramble siRNA. Three hepcidin-targeting siRNAs and one scramble siRNA for hepcidin were injected 24 h before hemorrhage induction, and hepcidin protein was injected 30 min before induction. The rats were neurologically evaluated at 24 h and euthanized at 72 h. Hepcidin, ferroportin-1, and ceruloplasmin protein expression were measured by immunohistochemistry and Western blotting. Brain water content, blood-brain barrier (BBB) leakage, non-heme tissue iron and Garcia scale were evaluated. Hepcidin expression increased in the cerebral cortex and hippocampus after experimental SAH (P < 0.05 compared to sham), while ferroportin-1 and ceruloplasmin decreased (P < 0.05). Hepcidin injection lowered the expression of ferroportin-1 and ceruloplasmin further but siRNA reduced the levels of hepcidin (P < 0.05 compared to SAH) resulting in recovery of ferroportin-1 and ceruloplasmin levels. Apoptosis was increased in SAH rats compared to sham (P < 0.05) and increased slightly more by hepcidin, but decreased by siRNA (P < 0.05 compared to SAH). SAH rats had lower neurological scores, high brain water content, BBB permeability, and non-heme tissue iron (P < 0.05). In conclusion, downregulation of ferroportin-1 and ceruloplasmin caused by hepcidin enhanced iron-dependent oxidative damage and may be the potential mechanism of SAH.
