CKD-EPI

Description

CKD-EPI

Usage

egfr.ckdepi(creatinine, age, sex, ethnicity,
  creatinine_units = "micromol/l",
  label_afroamerican = c("Afroamerican"), label_sex_male = c("Male",
  1), label_sex_female = c("Female", 0))

Arguments

creatinine

Numeric vector. Serum creatinine, could be expressed in "micromol/L", "mmol/L" or "mg/dL". Units of measurement should be defined in variable creatinine_units (if not defined explicitly by user, the default value is "micromol/L").

age

Numeric vector. Age, in years.

sex

Vector. The value of variable refers to the parameters label_sex_male and label_sex_female.

ethnicity

Vector. Ethnicity, specify in case of African-American patients. The value of variable refers to the parameter label_afroamerican.

creatinine_units

Character string. Units in which serum creatinne is expressed. Could be one of the following: "micromol/L", "mmol/L" or "mg/dL".

label_afroamerican

List. Label(s) for Afroamerican ethnicity.

label_sex_male

List. Label(s) for definition(s) of male sex.

label_sex_female

List. Label(s) for definition(s) of female sex.
