The pre-MRI (placebo: 1.91 ± 0.55; OT: 2.08 ± 0.55; t (110) = −1.57, p = 0.119) and post-MRI (placebo: 1.93 ± 0.42; OT: 2.09 ± 0.50, t (110) = −1.86, p = 0.067) cortisol levels between the placebo and OT groups were not significant although a trend towards significance emerged at post-MRI with higher cortisol levels in the OT group (see Fig. 2c ).
