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.
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
There is increasing evidence that vascular endothelial growth factor (VEGF) has a role in the development of vascular leakage in the hypoxic brain. Our recent work showed an anti-edematous effect of ghrelin on brain hypoxia. However, the underlying mechanisms by which ghrelin exerts its anti-edematous effect are still unclear. For this purpose, we examined the effects of ghrelin on VEGF expression in the hypoxic brain. Adult male Wistar rats were divided into acute or chronic controls, acute or chronic hypoxia, and ghrelin-treated acute or chronic hypoxia groups. Systemic hypoxia was induced in rats by a hypoxic chamber (O2 10-11 %) for 2 days (acute) or 10 days (chronic). Effects of ghrelin on VEGF expression were evaluated using immunoblotting. Our data revealed that acute and chronic hypoxia increased VEGF expression in both acute and chronic hypoxia (P < 0.001). Ghrelin significantly reduced this expression in hypoxic conditions (P < 0.001). Our findings demonstrated the beneficial effects of ghrelin might be mediated, at least in part, through a decline in VEGF production.
