SANS total score comparison at week 6 (post hoc tests from MM-ANCOVA):

• Oxytocin versus placebo: estimated mean difference in total scores ± s.e.: -1.02 ± 1.55; t= -0.66; df=46.9; p=0.51; Cohen's d = -0.10.
• Galantamine versus placebo: estimated mean difference in total scores ± s.e.: -1.45 ± 1.39; t= -1.04; df= 46.9; p=0.30; Cohen's d= -0.15.
