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

Intracerebral hemorrhage (ICH) can cause secondary brain damage through inflammation-related pathways. Thrombin and one of its receptors, protease activated receptor-1 (PAR-1); matrix metalloproteinase (MMP)-9; and aquaporin (AQP)-4 are stroke-related inflammatory mediators that have been implicated in ICH pathology. To further characterize the inflammatory response after ICH, we studied the temporal profile of the expression of these inflammatory mediators and assessed their potential correlation with brain edema formation after brain hemorrhage in rats. ICH was modeled by infusing autologous blood into the striatum. Then mRNA and protein expression was assessed over the course of 5 days. We found that the mRNA and/or protein expression of thrombin, PAR-1, AQP-4, and MMP-9 was upregulated between 2h and 5 days after ICH. Each reached a maximal level at day 2, except for AQP-4 protein, which peaked at day 5. Brain water content after ICH presented a similar trend; it was increased at 2h, peaked at day 2, and then decreased but remained elevated at day 5. Our data provide novel evidence that upregulation of these selected inflammatory mediators occurs very early and persists for several days after ICH, and that temporal patterns of expression of thrombin and AQP-4 are associated with brain edema formation. These findings have important implications for efforts to reduce secondary brain damage after ICH.
