Cantinotti et al., JASE 2014
BSA-adjusted Z scores derived from a large population of Caucasian neonates, infants, and toddlers calculated using "a rigorous statistical design": particular attention was paid to matters of skew/distribution and heteroscedasticity.

Note: the study population had the following characteristics:
- age range: (0 - 3)
- bsa range: (0.12 - 0.67)
Data entered for patients outside of these limits should be used with caution.
