claim: lung and gut microbiota are altered by hyperoxia and contribute to oxygen-induced lung injury in mice
evidence_1: during exposure of mice to hyperoxia, both lung and gut bacterial communities were altered, and these communities contributed to oxygen-induced lung injury.", "variation in lung inflammation correlates with variation in lung microbiota in hyperoxia-exposed mice.", "7.. hyperoxia alters microbial growth conditions in the mouse lung microenvironment.", "1.. hyperoxia alters lung microbiota in humans and in neonatal and adult mice.")
