Fig. 2 — Intra-infusion dissociative symptoms were transient in both groups (A) and did not correlate with peak change in depressive symptoms (B). Ketamine-group participants with history of dissociative symptoms experienced more intense but not more prolonged dissociative experiences during the infusion (C CADSS total score) or positive symptoms of psychosis (D BPRS positive symptom scale). For A, C, and D, error bars represent standard error of the mean. For B, shaded regions represent 95% confidence intervals. Abbreviations: Clinician-Administered Dissociative States Scale (CADSS), minutes (min), Beck Depression Inventory (BDI), Day 3 timepoint (D3), Brief Psychiatric Rating Scale Positive Symptom subscale (BPRS Positive Sx).
