Figure 6.

A comparison of the mean peak increases in systolic and diastolic blood pressure produced by intravenous versus oral administration of 50 mg lisdexamfetamine.

Means are adjusted for differences between the treatment groups at baseline. SEM was calculated from the residuals of the statistical model. Significantly different from appropriate placebo control group: *p < 0.05; **p < ;0.01. p-values for differences to compare to the same treatment by the oral and intravenous routes were obtained by the multiple t-test after fitting the data to a mixed linear model.

There were no significant differences between the peak increases in systolic and diastolic blood pressure evoked by 50 mg lisdexamfetamine administered intravenously and orally.
