Sedation was assessed by measuring cognitive speed and by asking participants to indicate on a 100 mm visual analog scale (VAS) how sedated they felt. Results are ranked from smallest to largest along the x-axis. Drug mediated slowing in cognitive speed (A) varied widely in participants being unaffected in some and being modestly affected in most participants. Subjective sedation scores (B) increased in all participants, but the magnitude of such increase varied remarkably. The solid and dashed lines indicate the median and the interquartile range, respectively.
