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) is a devastating form of stroke with high morbidity and mortality. Heme oxygenase-1 (HO-1), the key enzyme in heme degradation, is highly expressed after ICH, but its role is still unclear. In this study, we used an HO-1 inducer and inhibitor to test the role of HO-1 in different stages of ICH in vivo and in vitro. In the early stage of ICH, high HO-1 expression worsened the outcomes of mice subjected to the collagenase-induced ICH model. HO-1 increased brain edema, white matter damage, neuronal death, and neurobehavioral deficits. Furthermore, elevated HO-1 increased inflammation, oxidative stress, matrix metalloproteinase-9/2 activity, and iron deposition. In the later stage of ICH, long-term induction of HO-1 increased hematoma absorption, angiogenesis, and recovery of neurologic function. We conclude that HO-1 activation mediates early brain damage after ICH but promotes neurologic function recovery in the later stage of ICH.
