abstract: Computes predicted values and lower/upper limits of normal for pulmonary
  function tests according to American Thoracic Society (ATS) and European Respiratory
  Society (ERS) reference standards. Supports spirometry (Global Lung Function Initiative

  author correction <https://doi.org/10.1183/13993003.50010-2017>). Also assigns interpretive
  pattern labels (Normal, Non-specific, Obstructed, Restricted, Mixed) from spirometry
  and lung-volume measurements following the ERS/ATS 2022 interpretation algorithm,
