Animal-assisted resilience in space exploration: a human factors approach to astronaut behavioral health.
Article in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Space science has been developed through past and current missions of the International Space Station (ISS) and Artemis (I and II) in low Earth orbit and on the lunar surface. Numerous missions have used animals on test flights to better understand the physiological dangers of space flight for humans. A contemporary focus of space exploration is long-duration crewed travel to establish a Moon station and reach Mars. The astrotechnology of the human-less spaceflights (USA, Russia, ESA, UAE, China, and India) launched in 1965 (Mariner 4), has advanced enough to support the progressive colonization of the Red Planet with investigating equipment (Perseverance rover, Ingenuity helicopter, Hope orbiter, Tianwen-1 orbiter, and Chinese lander-rover). Are humans, then, ready to explore for deep space mission? What are major hazards that still need to be solved? Can animals play a novel role for humans in space? While the five factors of altered gravity, radiation, confinement (isolation), distance from Earth, and unknown hostile environments have been earnestly analyzed in the STEM field of space medicine, this paper initially examines the biological ripple effects of animal astronauts to mitigate risks for human astronauts as a psychological intervention model. The countermeasures of the well-being and space community security are determined considering the potential role of animals in reducing the emergence rate of behavioral health and performance decrements (loneliness, mental and emotional strain, fear, lethargy, lack of enthusiasm, and violence). This paper argues a rational hypothesis that if the engineering aspects of animal (dog) support does not reduce the scientific capabilities, the innovative policy of a 'human-pet companionship' can improve the cognitive, social, and physical resilience of the long-term astronauts in terms of neuroscience, safety, teamwork (communication), and mission success.
