The reference category of CD, PIL and ITB was non-CD (PIL & ITB), non-PIL (CD & ITB), and non-ITB (CD & PIL), respectively. The options with statistical insignificance in the three diseases are not given. The right section shows the scores of each option for each disease. CD: Crohn’s disease; In: Infinitesimal; ITB: Intestinal tuberculosis; M: Mucosa; MP: Muscularis propria; N/A: Not available; PIL: Primary intestinal lymphoma; S: Serosa; SM: Submucosa.
