Calculate creatinine clearance by the Cockcroft-Gault equation

Description

Calculate creatinine clearance by the Cockcroft-Gault equation

Usage

egfr.cg.cr(
  creatinine,
  age,
  sex,
  weight,
  creatinine_units = "micromol/l",
  label_sex_male = c("Male", 1),
  label_sex_female = c("Female", 0),
  max_age = 100
)

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.
weight	Numeric vector. Weight, kg.
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_sex_male	List. Label(s) for definition(s) of male sex.
label_sex_female	List. Label(s) for definition(s) of female sex.
max_age	Numeric. Maximal age suitable for the equation application, in years. By default is 100 years, but change this value in case you would like to apply equation to older persons.
