aCanadian Chronic Obstructive Lung Diseases Study
bDuration (measured in years) of persistent cough with no cold (i.e. has months in which they cough on most days and cough on most days of as much as 3 months each year)
cDuration (measured in years) of persistent phlegm with no cold (i.e. has months in which they produce phlegm on most days and produce phlegm on most days of as much as 3 months each year)
dCAT scale: 0 (no issue) – 5 (severe and affects ability to function). Higher CAT score increases the likelihood of Chronic Obstructive Pulmonary Disorder
