Figure 2: Long-term cognition by treatment group.

In survivors of critical illness, 3-month (upper panel) and 12-month (lower panel) global cognition, measured with the Telephone Interview for Cognitive Status (TICS), was not significantly different after treatment of delirium with haloperidol or ziprasidone as compared with placebo. Treatment effects were estimated after adjusting for prerandomisation predictors of cognition, including age, sex, race, baseline frailty, level of education, and baseline short IQCODE.
