Regression coefficients in the PLS model discriminating ADHD patients vs. control subjects. A large positive coefficient indicates an increase in the corresponding variable in ADHD patients vs. controls. In this model, most coefficients are negative, reflecting a general decrease in K_i values in the ADHD group. In particular, subcortical K_i values (dark blue columns) tend to be negatively related to the ADHD diagnosis. See list of abbreviations to identify the anatomical ROIs
