Number and proportion of subjects expressing Tenascin C outside the basal epithelial cells and basement membrane. Data is given for the three groups COPD, smoking controls (S) and non-smoking controls (NS). Tn C (b+c): All subjects with expression outside the basal epithelial cells and basement membrane. Tn C^©: Subjects with expression within connective tissue beyond the stroma underneath basal membrane. The number (n) of individuals in each category is presented underneath corresponding bar. The Odds ratio for a COPD patient to be in a higher category is statistically increased (P < 0.001) compared to subjects in the control groups.
