Data are presented as linear regression coefficients representing difference in vascular outcomes per litre increase in forced expiratory volume in 1 s based on the imputed datasets. Model 1: no adjustments; model 2: adjusted for age, sex, height and weight; model 3: adjusted for smoke exposure of the mother during pregnancy and 3 months postnatal growth; model 4: adjusted for current smoking of one of the parents, infections and allergy diagnosed by a general practitioner. Bold indicates statistical significance.
