Asthma outcomes in adults with Preserved Ratio Impaired Spirometry (PRISm): a cohort study
<title>Extract</title> Preserved Ratio Impaired Spirometry (PRISm) is usually characterized by reduced FEV<sub>1</sub> accompanied by a FEV<sub>1</sub>/FVC ratio above the lower limit of normal (LLN) [1, 2]. Some studies, however, have labeled it as a “restrictive” pattern when “PRISm” is accompanied by a reduction in Forced Vital Capacity (FVC) [3, 4]. Possibly, PRISm with normal FVC would be a borderline pattern between normal spirometry and airway obstruction because, in this scenario, a low FEV<sub>1</sub> value results in FEV<sub>1</sub>/FVC ratio close to the LLN; but without crossing the threshold that defines obstruction.
