  "Description": "A comprehensive, vectorised toolkit for estimating\nglomerular filtration rate (eGFR) and creatinine clearance from\nserum creatinine, cystatin C, or both. Implements adult,\npaediatric, and neonatal equations, including the Chronic\nKidney Disease Epidemiology Collaboration (CKD-EPI) equations\n(2009, 2012, 2021), the Modification of Diet in Renal Disease\n(MDRD) Study equation, Cockcroft-Gault, the European Kidney\nFunction Consortium (EKFC) equations, the Full Age Spectrum\n(FAS) equations, the Lund-Malmoe equations, the Berlin\nInitiative Study (BIS) equations, the Schwartz bedside\nequation, the Chronic Kidney Disease in Children Under 25 (CKiD\nU25) equations, the Caucasian, Asian, Paediatric, and Adult\n(CAPA) cystatin C equation, and a neonatal equation. Helpers\nfor body surface area, chronic kidney disease (CKD) staging\nfollowing the Kidney Disease: Improving Global Outcomes (KDIGO)\nguideline, and unit conversions are included. Methods are\ndescribed in Levey et al. (2009)\n<doi:10.7326/0003-4819-150-9-200905050-00006>, Inker et al.\n(2021) <doi:10.1056/NEJMoa2102953>, and Pottel et al. (2021)\n<doi:10.7326/M20-4366>.
