Our paper uses data on student course enrollments in the California Community Colleges system from 2015–16 through 2021–22 to explore how…

  • Prevalence of preserved ratio impaired spirometry and restrictive spirometry pattern in the general population

    Open AccessZ Xu, Wujian Xu et al.ARTICLEJournal of Global Health2026

    Background: Both preserved ratio impaired spirometry (PRISm) (defined as a forced expiratory volume in one second (FEV1) <80% of predicted, while the ratio of FEV1 to forced vital capacity (FVC) is ≥0.7) and restrictive spirometry pattern (RSP) (defined as FVC<80% of predicted, while the FEV1/FVC ratio ≥0.7) are associated with an increased risk of mortality. The global prevalence of PRISm and RSP in the general population remains unclear. Theref…
