Taxa detected in 80% of patients with and without PaO2/FiO2 ≤ 300. Taxa names represent the lowest level of identification of the corresponding OTU.
*Percent of total OTUs among 24 patients with PaO2/FiO2 > 300.
§Percent of total OTUs among 24 patients with PaO2/FiO2 ≤ 300.
NA indicates that these OTUs were not present among 80% of patients with PaO2/FiO2 > 300.
