A, Multivariate logistic regression model stratified by race comparing the odd ratio (OR) of asthma cases. B, Multivariate logistic regression model stratified by race comparing the OR of severe asthma exacerbations. Multivariate Poisson regression with robust variance stratified by race comparing the incidence rate ratio (IRR) of severe asthma exacerbations for cases with at least 1 severe exacerbation. OR/IRR is for a 10-ng/mL change in serum 25(OH)D concentration. All models are adjusted for age, sex, body mass index Z score, and month. Error bars indicate the 95% CI.
