Human Ghrelin Improves Vascular Integrity and Survival After Total Body Irradiation.
Article in Cells, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Exposure of healthy tissue to ionizing radiation (IR) occurs due to nuclear accidents and terrorism, as well as radiotherapy. The vascular endothelium is a key target of IR, and microvascular endothelial cells (ECs) are particularly vulnerable to radiation. IR induces EC activation leading to endothelial cell injury. Human ghrelin is a stomach-derived peptide with pleiotropic effects, including protection against inflammation. We hypothesize that human ghrelin improves survival in total body irradiation (TBI) and that ghrelin's protective effect could be mediated by attenuating endothelial cell injury. To test this, mice were exposed to TBI and after 24 h were treated subcutaneously with human ghrelin once daily for 4 days and monitored for 30 days. The survival rate of the human ghrelin-treated group was significantly higher than that of the vehicle group. Subsequently, human ghrelin treatment showed an effective dose modification factor of 1.0681. On day 4 after TBI, human ghrelin significantly attenuated EC permeability in the lungs and improved tight junction protein ZO-1 expression. Human ghrelin also improved ZO-1 and Claudin5 expression in primary mouse lung vascular endothelial cells. Taken together, these results indicate that human ghrelin improves survival after TBI, and its survival benefit is in part due to the attenuation of EC permeability and microvascular barrier dysfunction.
