a trend toward significancep = 0.07
Supplementary analyses of Psilocybin + HE vs psilocybin + HE + B3 * Time revealed a trend toward significance (F (1, 427) = 3.26, b = − 0.56 , p = 0.07), and the three-way Psilocybin + HE vs psilocybin + HE + B3 * Time * Age interaction was identified (F (1, 427) = 6.71, b = 0.66 , p = 0 . 01), indicating that effects were more pronounced among older respondents.
