# egfr 1.1.0

* Fixed the Full Age Spectrum (FAS) creatinine equation (`egfr_fas_cr()`) for
  ages over 40: the creatinine-ratio exponent is now correctly -1 (a plain
  reciprocal) as published in Pottel et al. (2016), rather than -0.88. This
  changes returned eGFR values for patients older than 40.
* `egfr_ekfc_cr()`, `egfr_ekfc_cys()`, and `egfr_ekfc_cr_cys()` gain an
  optional `q` argument (`q_cr` / `q_cys` for the combined equation) to supply
  a population-, assay-, or individual-specific reference Q value. The default
  (`NULL`) continues to use the built-in EKFC reference Q, so existing code is
  unaffected.

# egfr 1.0.0

# egfr 0.1.0

* Initial release.
* 20 eGFR / creatinine-clearance equations:
  CKD-EPI 2021 (creatinine, cystatin C, combined), CKD-EPI 2009, CKD-EPI 2012
  cystatin C, MDRD, Cockcroft-Gault, EKFC (creatinine, cystatin C, combined),
  FAS, Lund-Malmoe, Berlin Initiative Study, Schwartz bedside, CKiD U25
  (creatinine, cystatin C, combined, extended), CAPA, and neonatal eGFR.
* Helpers: `bsa()`, `ckd_stage()`, and creatinine unit conversion.
