Log-transformed outcome so estimates and CIs are ratios of geometric means rather than differences of arithmetic means. Log-transformed CRP was used as the independent variable of interest Analyses are adjusted for sex, height, changes in BMI and pack years smoking between ages 32 and 38 years. DL_CO and DL_CO/VA analyses are also adjusted for changes in exhaled carbon monoxide and haemoglobin.

Sex-BMI interaction included in the model.
