Berlin Initiative Study (BIS1) creatinine eGFR (2012)

Source: R/ekfc.R
egfr_bis_cr.Rd

Estimates GFR from serum creatinine using the BIS1 equation (Schaeffner et al., 2012), developed in an elderly (>= 70 years) German cohort.

Usage

egfr_bis_cr(
  creatinine,
  age,
  sex,
  creatinine_units = "mg/dl",
  label_sex_male = "male",
  label_sex_female = "female"
)

Arguments

creatinine

Numeric vector of serum creatinine.

age

Numeric vector of age in years.

sex

Vector of sex labels (see label_sex_male/label_sex_female).

creatinine_units

Units of creatinine: "mg/dl" (default) or "umol/l".

label_sex_male, label_sex_female

Values in sex that denote male and female records. Defaults to "male"/"female".

Value

Numeric vector of eGFR in mL/min/1.73m^2.
