ckdepi_2009_egfr.Rd

[Deprecated]

This function is deprecated; use egfr() with method = "CKDEPI 2009".

Usage

ckdepi_2009_egfr(sexf, raceb, age, creat)

Arguments

sexf

boolean value of sex Female: TRUE, Male: FALSE

raceb

boolean value of Race == Black: Black: TRUE, Other: FALSE

age

age of subject (years)

creat

creatinine levels of subject (mg/dL)

Value

the eGFR value (mL/min/1.73m2)

Details

The CKD-EPI 2009 equation: $$eGFR = 141 \cdot \min(S_{cr}/\kappa, 1)^\alpha \cdot \max(S_{cr}/\kappa, 1)^{-1.209} \cdot 0.993^A \cdot 1.018^F \cdot 1.159^B$$

where:

  • \(S_{cr}\) = serum creatinine (mg/dL)

  • \(\kappa\) = 0.7 (female) or 0.9 (male)

  • \(\alpha\) = -0.329 (female) or -0.411 (male)

  • \(A\) = age (years)

  • \(F\) = 1 (female) or 0 (male)

  • \(B\) = 1 (Black) or 0 (other)

Examples

e <- egfr(TRUE, TRUE, 24, 1, method = "CKDEPI 2009")
