GFR is estimated with the 6-parameter Modification of Diet in Renal Disease (MDRD) study equation.
MDRD6(creatinine, sex, age, albumin, BUN, ethnicity, method = 'IDMS')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
Numeric vector with serum or plasma albumin in g/dl
Numeric vector with blood urea nitrogen levels in mg/dl
Numeric vector with 0 for non-Black and 1 for Black individuals
Defaults is 'IDMS' for IDMS-traceable creatinine; write 'other' if not IDMS
