Table 1. Significant correlations between plasma levels of anti-ClpB IgG or IgM and behavioral traits in eating disorder patients and Ctr. assayed by the Eating Disorder Inventory-2.

ClpB IgG (Ctr.)	Maturity fears, r=−0.31*	Impulse regulation, r=−0.26*	Social insecurity, r=−0.26*
ClpB IgG (AN)	Body dissatisfaction, r=0.4*	Drive for thinness, r=0.35*	Perfectionism, r=0.38*
ClpB IgM (AN)	Ineffectiveness, r=−0.42*	Interpersonal distrust, r=−0.58**	Social insecurity, anhedonia, r=−0.52**, r=−0.35*
