Relative abundance of particular taxa in Crohn’s disease (CD) patients based on prognosis. (A) Lachnospiraceae and (B) Ruminococcus gnavus. Better prognosis is defined as patients who did not consume biologic agents including anti-tumor necrosis factor (TNF)-α agents or surgical treatment after fecal sampling and worse prognosis is defined as patients who either were administered biologic agents including anti-TNF-α agents or required surgical treatment after fecal sampling (n=9). Lachnospiraceae and R. gnavus were significantly more abundant in the better prognosis group compared to the worse prognosis group.
