Design outcomes

Primary

Measure	Time frame
Multivariate statistics will be applied. The data will be combined with those of Essen and Gent for the genetic analyses. If 322 trios of patients with both ADHD and SUD are available, this will offer 80% power or more to detect alleles for SUD that increase the risk with 70% (a relatively large risk of 1.7) using an alpha of 0.05.	—
