  1. COPD chronic obstructive pulmonary disease. Results are expressed as number of participants and (column percentage). Between-group analysis performed using chi-square test or Fisher’s exact test (a).The group “chronic obstruction” also contains the subjects with both “chronic obstruction and possible restriction”. The group “reversible obstruction” also contains the subject with both “reversible obstruction and possible restriction”
