Note. Mean ± Standard Deviation (observed).
AST=associative striatum; DD=dual-diagnosis; post-amph=post-amphetamine; postCA=postcommissural caudate; postPU= postcommissural putamen; preDCA=precommissural dorsal caudate; preDPU=precommissural dorsal putamen; STR=whole striatum; VST=ventral striatum.
Group comparisons of estimated marginal means derived from linear mixed modeling (see text) with the exception of AST and STR; these composite regions were compared with independent-samples t-tests.
