All base models included age, gender, height, race/ethnicity, and LRIs. The number of observations for the prealbuterol FEV₁ model was 1676; the number of individuals included in the analysis was 646, with an average number of observations per individual of 2.6. B, model coefficient; Ref, reference group in the model.
