Smokers with preserved ratio impaired spirometry (PRISm) physiology have been shown to have significant probability of progressing to classic obstruction, defined as Global Initiative for Chronic Obstructive Lung Disease, or GOLD, Stages 2, 3, and 4. Nonsmokers with the same physiology have less probability of progressing to obstructive physiology. However, the fraction of nonsmokers that remain stable in preserved ratio impaired spirometry, or that show progressive restrictive changes or show changes toward obstruction, has not yet been defined.
