Response selection (go) results: Clusters showing significantly different BOLD response at baseline between adolescents who transitioned into substance use (TU; n=21) versus those who remained continuously non-users (CON; n=17) (each cluster was ≥ 32 contiguous voxels, ≥ 864 μl, with each voxel differing at α < .025)a.

a
At the significance threshold used in Table 2, none of these clusters remained significant.
b
Coordinates refer to peak group difference.
c
In no region did TU show more go response than CON.
