  "Description": "Implementation of various spirometry equations in R,\ncurrently the GLI-2012 (Global Lung Initiative; Quanjer et al.\n2012 <doi:10.1183/09031936.00080312>), the race-neutral GLI\nglobal 2022 (Global Lung Initiative; Bowerman et al. 2023\n<doi:10.1164/rccm.202205-0963OC>), the NHANES3 (National Health\nand Nutrition Examination Survey; Hankinson et al. 1999\n<doi:10.1164/ajrccm.159.1.9712108>) and the JRS 2014 (Japanese\nRespiratory Society; Kubota et al. 2014\n<doi:10.1016/j.resinv.2014.03.003>) equations. Also the\nGLI-2017 diffusing capacity equations\n<doi:10.1183/13993003.00010-2017> are implemented. Contains\nuser-friendly functions to calculate predicted and LLN (Lower\nLimit of Normal) values for different spirometric parameters\nsuch as FEV1 (Forced Expiratory Volume in 1 second), FVC\n(Forced Vital Capacity), etc, and to convert absolute\nspirometry measurements to percent (%) predicted and z-scores.",
