Enhancing Astronaut Resilience: The Role of Elevated ROS in Adapting to Space Radiation.
Article in Journal of biomedical physics & engineering, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The microgravity environment and high radiation levels in space lead to a significant increase in Reactive Oxygen Species (ROS) production compared to Earth, which can have detrimental effects on astronaut health over time. This study examines the hypothesis that high levels of ROS in living organisms in space may aid pre-selected astronauts' cells in adapting to the intense radiation encountered during missions to Mars and beyond. By looking at evolutionary biology and past radiation events like the Chernobyl disaster, we suggest that increased ROS could trigger adaptive responses similar to those seen in radiation-resistant organisms such as tardigrades. This paper explores the dual nature of ROS as both harmful agents and vital signaling molecules, evaluating their potential to enhance DNA repair, boost antioxidant defenses, and alter mitochondrial metabolism. We aim to see if managing ROS could be a strategy to prepare astronauts' cells for space travel, using cytogenetic tests to find individuals with strong adaptive responses.
