Calculate eGFR by all creatinine-based equations for adults

Description

Calculate eGFR by all creatinine-based equations for adults

Usage

egfr.all_adults.cr(
  creatinine,
  age,
  sex,
  ethnicity = NA,
  creatinine_units = "micromol/l",
  label_sex_male = c("Male", 1),
  label_sex_female = c("Female", 0),
  label_african = c("Afroamerican"),
  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.
ethnicity	Vector. Ethnicity. If no ethnicity will be defined, the calculation will use coefficients for Caucasian subjects. Specify ethnicity labels in the function parameter label_african.
creatinine_units	Character string. Units in which serum creatinine 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.
label_african	List. Label(s) for African ethnicity. Required only by race-specific equations.
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.

Examples

# for a single patient
egfr.all_adults.cr (creatinine = 1.4, age = 60, sex = "Male", 
  creatinine_units = "mg/dl")
# for a dataset - see vignettes for details
# egfr.all_adults.cr (creatinine = dta$scr, age = dta$age, sex = dta$sex, 
#  creatinine_units = "mg/dl")
