GFR is estimated with the Bedside Schwartz equation for Children based on IDMS serum or plasma creatinine.
This equation is valid in the 1-17 years age range.
Schwartz.Bedside(creatinine, ht, age)A numeric vector with eGFR values in ml/min/1.73 \(m^2\).
Numeric vector with serum or plasma creatinine values in mg/dl
Numeric vector with height in cm
Numeric vector with age in years
