The evolution of superbugs in space: a genomic perspective on pathogens in the International Space Station environment.

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
Microgravity, pressure, and temperature variations in the International Space Station (ISS) create conditions leading to the emergence of superbugs. Due to technical issues in spacecraft, astronauts are forced to stay in ISS for extended periods; prolonged stay and exposure in stressful ISS environment weakens their immune systems, increasing susceptibility to infections. The presence of hypervirulent and antibiotic-resistant pathogens in space station is a worrisome feature as these might cause serious life-threatening infections in astronauts staying in high stress environments with weakened immune systems. In the present study, we compared antimicrobial resistance genes (ARGs) and virulence factors (VFs) in bacterial genomes from ISS with Earth counterparts. ISS genomes exhibited elevated counts of defense-related genes, particularly in E. ludwigii and E. cancerogenus. Among genes uniquely found in ISS genomes, CRISPR-Cas system components were notably prevalent. Though Earth genomes harbored higher number of ARGs overall, several species from ISS possessed modestly higher ARG counts. VFs profiling showed a slightly lower count in ISS genomes, but P. conspicua, E. ludwigii, and K. pneumoniae from ISS carried exclusive VFs linked to metal ion uptake and secretion systems, suggesting environment-driven functional adaptations. The adaptation of pathogenic bacteria in ISS is alarming and therefore periodic monitoring of bacterial genomic surveillance is important. Our findings shed light on genomic profiles in bacterial strains from both ISS and Earth, enhancing our understanding of the bacterial pathogens' potential impact on drug resistance and pathogenicity in space-missions and the possible threat of spread from ISS.
