abstract: Implements the Kidney Failure Risk Equation (KFRE; Tangri and colleagues
  (2011) <https://doi.org/10.1001/jama.2011.451>; Tangri and colleagues (2016) <https://doi.org/10.1001/jama.2015.18202>)
  to compute 2- and 5-year kidney failure risk using 4-, 6-, and 8-variable models.
  Includes helpers to append risk columns to data frames, classify chronic kidney
  disease (CKD) stages and end-stage renal disease (ESRD) outcomes, and evaluate and
  plot model performance.
