A small, significant negative correlation between medial OFC GM volume and avoidance of bad decks was observed across groups (r=-.39, p=.01,1-tail). After adjusting for age, education, and IQ, the correlation remained significant (r=-.35, p=.03, 1-tail). The correlation was higher in controls (r=-.37) than SDI (r=-.22) but due to small numbers was not significant within group (Figure 3).
