Low-risk participants and factor 3 (P300) loadings. Individuals in group 1 with the largest negative loadings (.80 ± .4) have the lowest amplitude, while those in group 2 are in the midrange of factor loading (.05 ± .2) and group 3 with the largest positive loadings (.94 ± .5) represent the largest P300 amplitude. Note that P300 amplitude has only a minimal effect on SUD outcome by age 24 in these individuals. SUD, substance use disorder.
