Evidence-Base and Validation.
The FASD 4-Digit Code was established from an extensive evidence base that included testing its performance for 4 years in the FASD Clinic on 1,014 patients before its release in 1997. We have continued to extensively test (validate) the performance of the FASD 4-Digit Code on thousands of patients over the past 20 years. The evidence-base that validates the performance of the 4-Digit Code is presented in the following research publications and presentations:
