Looking at the COPD spectrum through “PRISm”

A comment on the study "Preserved ratio impaired spirometry (PRISm) is a prevalent, neglected condition whose prognosis is close to that of COPD" by Wijnant et al. Given that PRISm resembles COPD in term of reduction in FEV1, but not in terms of FEV1/FVC r...
