Table 2.

Continuous age-normalization for serum creatinine: the transformation for serum creatinine concentrations is presented here as a function of age and raw value, e.g., for a 15-month old patient with a serum creatinine level of 1.2, the value for the renal component of the CAN-SOFA score would be 3.33, as opposed to standard pediatric SOFA score of 3.
