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