Table 4. OTU level detection differences.

Taxa Detection Rate Among Patients with PaO2/FiO2 ≤ 300 (# of patients) Detection Rate Among Patients with PaO2/FiO2 > 300 (# of patients) P-Value
OTU47: Prevotella melaninogenica 19 11 0.037
OTU18: Corynebacterium spp. 6 14 0.040
OTU115: Fusobacterium spp. 17 9 0.043
