Modification of Diet in Renal Disease eGFR calculation

Usage

mdrd_egfr(sexf, raceb, age, creat)

Arguments

sexf: a boolean representing if the patient is female.
raceb: a boolean representing if the patient is black.
age: the age of the patient in years
creat: the serum creatinine levels in mg/dL

Value

the eGFR in mL/min/1.73 m^2

Examples

e <- mdrd_egfr(TRUE, TRUE, 24, 1)

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 = mdrd_egfr(SEXF, RACEB, AGE, CREAT))
df

#> 2 FALSE FALSE  24     1 91.80264
#> 3  TRUE  TRUE  23     2 37.42185
