Forest plot 15 is a metagraph comparing the incidence of withdrawals due to adverse events between patients receiving haloperidol versus ziprasidone. Six trials pooled data from 1,551 patients and found that withdrawals due to adverse events occurred significantly less with ziprasidone (MD=1.73, 95 percent CI, 1.30, 2.32).
