Association between lung function and augmentation index by multivariate analysis.

Carotid AIx75 is the dependent variable, lung function measures are the main independent (explanatory) variables, and all models include sex, height, maternal smoking status during pregnancy, ETS exposure during childhood, and randomization groups (for house dust mite avoidance and dietary interventions) as covariates. The partial R2 measures the marginal contribution of that lung function measure when the other explanatory variables are already included in the multiple linear regression model and the b-coefficient represents the change in AIx75 in % per unit change in explanatory variable.
