Parameter estimates (95% CIs) and likelihood ratio test (LRT) p values for the effect of deprivation on weight-for-age SD-score trajectories, BMI SD-score trajectories, %predicted FEV1 and cPA after adjustment for sex, genotype, year of birth, ethnicity, deprivation, diagnosis by MI and pancreatic insufficiency. The model for weight was further adjusted for a main effect of NBS and an interaction effect of NBS and age; the models for %FEV1 and cPA were adjusted for an NBS main effect. All numbers were rounded to two digits
