Primary outcomes

• PANSS-EC Change From Baseline — 2 hours
  The Positive and Negative Syndrome Scale-Excited Component (PANSS-EC) comprises 5 items associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement; each scored 1 (min) to 7 (max). The PANSS-EC, the sum of these 5 subscales, thus ranges from 5 to 35. Individuals were eligible if they had a PANSS-EC of ≥14 (out of 35) and a score ≥4 (out of 7) on at least 1 of the 5 items.
