Association between allergy burden at 16y and any AP-FGID and IBS at 16y. The number of concurrent allergy-related diseases (including asthma, rhinitis, eczema, and food hypersensitivity) was used as a proxy for allergy burden at 16y. Associations were assessed in a binomial generalized linear model with a log link function and adjusted for sex. Children with no AP-FGID at age 16 years were used as the reference group in all analyses. AP-FGID, abdominal pain-related functional gastrointestinal disorders; CI, confidence interval; IBS, irritable bowel syndrome; RR, relative risk; y, years
