Note. Significant regression coefficients (p<.05) are in boldface. By convention, y-standardized regression coefficients of dummy coded variables of the sizes 0.2, 0.5, and 0.8 indicate small, medium, and large effect sizes, respectively. MIMIC  =  multiple indicators multiple causes; DIF  =  differential item functioning; PET  =  positron emission tomography (0 =  no PET, 1 =  PET); Female (0 =  male, 1 =  female); OAV  =  Altered state of consciousness rating scale version (0 =  OAV, 1 =  5D-ASC); Psilocybin (0 =  1.5–1.7 mg/kg MDMA or 6–12 µg ⋅ kg⁻¹⋅ min⁻¹ ketamine, 1 = 115–315 µg/kg psilocybin); Ketamine (0 = 1.5–1.7 mg/kg MDMA or 115–315 µg/kg psilocybin, 1 = 6–12 µg ⋅ kg⁻¹ ⋅ min⁻¹ ketamine).
