Fig 1 Mean lung function parameters and 95% CI by quartiles of serum CC-16 levels (μg/L). Asterisks represent P values obtained by comparing the mean lung function level for each quartile of the serum CC-16 level with the first quartile as reference (*P < .10, **P < .05, and ***P < .001).

Fig E1 Prevalence of asthma and airflow limitation by quartiles of serum CC-16 levels. Asterisks represent P values obtained by comparing the unadjusted odds ratio of having the outcome for each quartile of the serum CC-16 level, using the first quartile as reference. LLN, Lower limit of normal. *P < .10, **P < .05, and ***P <.001.

Fig E2 Adjusted regression coefficients (beta) and 95% CI for the association between serum CC-16 levels and lung function parameters, estimated through a multivariate linear regression model, stratified by asthma status. The P values refer to the interaction between asthma status and serum CC-16 levels.

Fig E3 Adjusted regression coefficients (beta) and 95% CI for the association between serum CC-16 levels and lung function parameters, estimated through a multivariate linear regression model, stratified by smoking status. The P values refer to the interaction between smoking status and serum CC-16 levels.
