Usage

egfr(sexf, raceb, age, creat, cystc, height, method = "CKDEPI 2021")

Arguments

sexf

a boolean representing if the patient is female.

raceb

a boolean representing if the patient is black.

age

the age of a patient in years.

creat

the serum creatinine levels in mg/dL.

cystc

the cystatin C levels in mg/L - only used in CKDEPI 2021 cystatin method

height

the height of a patient in cm.

method

a string specifying the method to use. Available options are "CKDEPI 2009", "MDRD", "CKDEPI 2021", "Schwartz".

Value

the eGFR calculated based on method.

Examples

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

df <- data.frame(
  "SEXF" = c(TRUE, FALSE, TRUE, FALSE),
  "RACEB" = c(FALSE, FALSE, TRUE, FALSE),
  "AGE" = c(24, 24, 23, 24),
  "CREAT" = c(1, 1, 2, 1)
)
df <- dplyr::mutate(df, egfr = egfr(SEXF, RACEB, AGE, CREAT, "CKDEPI 2009"))
df
