The trial was randomized and quadruple-blind, included both placebo and active control groups, and enrolled 593 participants. Its primary clinical symptom endpoint was PANSS-T change, with mean changes of -12.0 for iloperidone versus -7.1 for placebo, but statistical significance of the comparison is not reported, so the result remains unclear.
