CKiD U25 combined creatinine + cystatin C eGFR — egfr_ckid_u25_cr

Arithmetic mean of the CKiD U25 creatinine (egfr_ckid_u25_cr()) and cystatin C (egfr_ckid_u25_cys()) estimates.

Usage

egfr_ckid_u25_cr_cys(
  creatinine,
  cystatin,
  age,
  sex,
  height,
  creatinine_units = "mg/dl",
  height_units = "cm",
  label_sex_male = "male",
  label_sex_female = "female"
)

Arguments
