Longitudinal results: mixed model regression estimates for forced expiratory volume in 1 second (FEV1) in 1995 (intercept) and for the mean decline in FEV1 per year (slope)

Estimates are shown as mean differences between the subgroups malnutrition present v absent and Pseudomonas aeruginosa infection present v absent, respectively, and between male and female adolescents.
