# Six-parameter MDRD study equation

### Description

GFR is estimated with the 6-parameter Modification of Diet in Renal Disease (MDRD) study equation.

### Usage

1 | ```
MDRD6(creatinine, sex, age, albumin, BUN, 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 |

`albumin` |
Numeric vector with serum or plasma albumin in g/dl |

`BUN` |
Numeric vector with blood urea nitrogen levels in mg/dl |

`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*.
