Results are from logistic regression analysis of each severity indicator and the risk of anxiety. Results are expressed as OR per 0.5 SD increment of each severity indicator (95% CI). Multivariable analysis adjusts for age, sex, race, educational attainment, household income and smoking history.
COPD, chronic obstructive pulmonary disease; FEV1, forced expiratory volume in 1 s.
