Vomiting scores across the study. Vomiting scores over the course of the study are provided for both groups, with individual patient scores, daily means and smoothed average response trajectories along with 95% confidence bands. During session 1, a slight, non-significant decrease in average vomiting score was observed; however, the decrease with stimulation (group A) was greater. Scores did not return to baseline for either group during the washout period. During session 2, vomiting scores slightly decreased with stimulation (group B) and slightly increased without it (group A) (see Table 2).
