Weight-for-length, early weight-gain velocity and atopic dermatitis in infancy and at two years of age: a cohort study

Table 3 Number of children with atopic dermatitis (AD) and adjusted odds ratio (OR; 95% CI) for AD at enrolment (mean age 5.1 months) and at two-year follow-up visit (mean age 24.6 months) in 346 children (after excluding children with missing data). The table shows the final models after Hosmer’s stepwise procedure eliminating potential confounding variables^a
