CRP, C-reactive protein; FEV₁, forced expiratory volume in one second; BMI, body mass index.
Coefficients refer to the change in FEV₁ in ml for each standard deviation increase in log-CRP. Analyses exclude pregnant women. *Adjustment for current (past year) smoking and asthma. BMI, body mass index (kg/m²).
