Chronic fatigue is associated with increased disease-related worries and concerns in inflammatory bowel disease

Data are presented as mean (SD), calculated with independent samples t tests. RFIPC: Rating form of inflammatory bowel disease patient concerns; CD: Crohn’s disease; UC: Ulcerative colitis; CF: Chronic fatigue. Cohen`s d effect size: small, d = 0.2; medium, d = 0.5; large, d = 0.8.
