Four-parameter MDRD study equation
Description
GFR is estimated with the 4-parameter Modification of Diet in Renal Disease (MDRD) study equation.
Usage
MDRD4(creatinine, sex, age, ethnicity, method = "IDMS")Arguments
creatinine |
Numeric vector with serum or plasma creatinine values in mg/dl |
sex |
Numeric vector with 0 for females and 1 for males |
age |
Numeric vector with age in years |
ethnicity |
Numeric vector with 0 for non-Black and 1 for Black individuals |
method |
Defaults is 'IDMS' for IDMS-traceable creatinine; write 'other' if not IDMS |
Value
A numeric vector with eGFR values in ml/min/1.73 m^2.
