Fischer’s exact test P value is equal to 1 for the gender difference among CD, UC and HC in both discovery and validation set. Kruskal-Wallis test P value for the age difference among CD, UC and HC in discovery and validation set were 0.3159 and 0.1737 respectively. CD: Crohn’s disease; UC: Ulcerative colitis; HC: Healthy control.
