Regression coefficients in the PLS model relating attention score to regional Ki values in the ADHD group only. Large positive coefficients indicate a positive correlation, i.e., the larger the Ki, the higher the attention score. Large negative coefficients suggest an inverse relationship, where high Ki values are associated with low values in the attention score.

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 Ki values in the ADHD group. In particular, subcortical Ki values (dark blue columns) tend to be negatively related to the ADHD diagnosis. See list of abbreviations to identify the anatomical ROIs

Partial least squares regression (PLS) discriminant analysis distinguishes ADHD patients (red circles) from control subjects (black squares). Each object in the graph represents one individual. For each individual, the position in the plot is a compact representation of all regional Ki data collected. Objects that appear close to each other are generally similar across all variables. In this case, ADHD patients and controls form separate groups, reflecting underlying group differences in regional Ki values.
