Difference (χ², P-values displayed) between the genotype distributions and allelic frequencies, related to age at diagnosis, in individuals with CD or UC compared with the healthy population. UC: Ulcerative colitis; CD: Crohn’s disease; NS: Not significant; EPX: Eosinophil protein X; ECP: Eosinophil cationic protein.
