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

Autophagy occurs in the brain after intracerebral hemorrhage (ICH) and thrombin contributes to ICH-induced brain injury and cell death. In this study, we investigated whether thrombin may activate autophagy (in vivo and in cultured astrocytes) and its potential role in ICH. Autophagy was examined using electron microscopy, conversion of light chain 3(LC3) from the LC3-I form to LC3-II, cathepsin D Western blotting and monodansylcadaverine (MDC) staining to detect autophagic vacuoles. 3-Methyladenine (3-MA) was used as an autophagy inhibitor. In vivo, we found that intracaudate injection of thrombin increased conversion of LC3-I to LC3-II, cathepsin D levels, and formation of autophagic vacuoles in the ipsilateral basal ganglia. ICH-induced upregulation of LC3-I to LC3-II conversion and cathepsin D levels was reduced by a thrombin inhibitor, hirudin. In cultured astrocytes, thrombin enhanced the conversion of LC3-I to LC3-II and increased MDC-labeled autophagic vacuoles. 3-MA inhibited thrombin-induced autophagic vacuole formation and exacerbated thrombin-induced cell death. These results indicate that thrombin activates autophagy in the brain and that thrombin has a role in ICH-induced autophagy.
