Analyses by logistic regression by using atopic sensitization as the dependent variable, and oral habit in childhood as the main predictor. Analyses are adjusted for sex alone, or multiply adjusted for sex, breastfeeding, parental atopy, parental smoking, household crowding, cat and dog ownership, and SES. The differences in n values are caused by missing data for outcome measures or covariates. CI, confidence interval.
