GFR is estimated with the CKD-EPI Study equation based on serum creatinine without the ethnicity coefficient.
CKDEpi2021.creat(creatinine, sex, age)A numeric vector with eGFR values in ml/min/1.73 \(m^2\).
Numeric vector with serum or plasma creatinine values in mg/dl
Numeric vector with 0 for females and 1 for males
Numeric vector with age in years
