Figure 2. Ability of inflammatory mediators to predict changes in patient clinical features in a) stable-state (n = 18) and b) at exacerbation (n = 30).

A linear regression model was used and adjusted for age, sex, body mass index and smoking pack-years. The inflammatory mediators were used as independent variables to predict changes in all assessed clinical features. * Denotes a positive association. BP: blood pressure, MAP: mean arterial pressure, Abs: absolute, AP: augmentation pressure.
