Calculate eGFR by all creatinine-cystatin-based equations for adults

Usage

egfr.all_adults.cr_cys(
  creatinine,
  cystatin,
  age,
  sex,
  creatinine_units = "micromol/l",
  cystatin_units = "mg/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").
cystatin: Numeric vector. Serum cystatin, could be expressed in "mg/L" or "nanomol/L". Units of measurement should be defined in variable cystatin_units (if not defined explicitly by user, the default value is "mg/L").
age: Numeric vector. Age, in years.
sex: Vector. The value of variable refers to the parameters label_sex_male and label_sex_female.
creatinine_units: Character string. Units in which serum creatinine is expressed. Could be one of the following: "micromol/L", "mmol/L" or "mg/dL".
cystatin_units: Character string. Units in which serum cystatin is expressed. Could be one of the following: "mg/L" or "nanomol/L"
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.

Value

numeric eGFR expressed in ml/min/1.73m².
