In a retrospective cohort study by Kurashima et al, the presence of CT-diagnosed emphysema predicted poor prognosis in patients who had COPD and asthma with chronic airflow obstruction (CAO). Patients with asthma without emphysema had the best prognosis, followed by those with asthma with emphysema, COPD without emphysema, and COPD with emphysema. [42]
