Figure 1. Flow of Patients Through the GWPCARE2 Trial.

Patients in the placebo group were pooled for a combined total of 65 patients; 32 were assigned to receive a volume equivalent to the 10-mg/kg/d cannabidiol dose and 33 were assigned to receive a volume equivalent to the 20-mg/kg/d cannabidiol dose. Among the 86 patients excluded, 3 had multiple reasons for exclusion. One patient randomized to the 10-mg/kg/d dose was not treated and was subsequently withdrawn by the investigator.
