  • ↵* Atopic dermatitis was diagnosed in 10 children who were not included in the analyses because intrapartum antibiotic exposure time could not be determined.

  • ↵† Relative risks (RRs) were calculated when compared with no intrapartum exposure (n = 364) and atopic dermatitis (n = 100).

  • CI, confidence interval.
