MDRD4: Four-parameter MDRD study equation

In nephro: Biostatistics utilities for nephrology

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.
