Three enterotypes of fecal taxa in patients with non-OSAHS, compared with OSAHS subjects

Microbiome distribution across three enterotypes (A). The fecal microbiota showed significant differences in the following genera: Bacteroides (enterotype 1) (B), Ruminococcus (enterotype 2) (C), and Prevotella (enterotype 3) (D). Statistical analysis was performed with the Kruskal–Wallis test. *P<.05, **P<0.01 compared with the control group or OSAHS groups. Control: patients with AHI ≤ 5 events/h were considered as non-OSAHS; Group 1: patients with 5 < AHI ≤ 15 were considered as mild OSAHS; Group 2: patients with 15 < AHI ≤ 30 were considered as moderate OSAHS; Group 3: patients with AHI ≥ 30 were considered as severe OSAHS.
