Associations between blood AWT score and CT airway wall thickness

Variables Beta (95% CI) Adjusted P value
All subjects (n= 2396) 0.25 (0.16–0.34) <0.001
COPD (n=1028) 0.26 (0.11–0.42) 0.036
Control (n=1368) 0.15 (0.05–0.26) 0.13

CT airway wall thickness standardized using z score. Linear regression adjusted for age, sex, race, body mass index, smoking status, CT scanner model, emphysema (%). Beta denotes regression coefficient, which is the change in the outcome variable associated with a 1 unit increase in blood AWT score when all other variables were held constant.

P value adjusted for multiple testing using Holm-Bonferroni correction.
