ARR, adjusted relative risk; CI, confidence interval.

No/low sensitization trajectory was the reference group for relative risk.

Sex, ethnicity, maternal education level and family history of allergy were adjusted in the multivariate Poisson regression with robust error variance for each allergic comorbidity.
