  1. Demographic data analyses were performed on reduced sample sizes due to missing values. Specifically, age data were available for 128 participants (out of 131 total; missing 3), education data for 124 participants (missing 7), and sex data for 128 participants (missing 3; 2 in HC group, 1 in CUD group). Statistical tests used include chi-square (χ2) for categorical variables and t-tests for continuous variables. Three participants were excluded for missing age values. Seven participants were excluded for missing education values. Three participants (2 HC, 1 CUD) missing sex values, male/female were the only available options. Head motion calculated using mean framewise displacement (mm). Asterisk (*) = significant group difference \((p < 0.05)\).
