By-study comparison of baseline-to-endpoint change in productivity level in olanzapine-treated versus other-treated chronically ill patients with schizophrenia. Comparison between olanzapine and each of the other antipsychotics--aripiprazole, haloperidol, risperidone, quetiapine, and ziprasidone--demonstrated that olanzapine was consistently associated with higher mean changes in baseline-to-endpoint productivity level. Productivity level was assessed by study investigators on a 5-point scale, with scale scores corresponding to how often functional activities can be performed: 1, no useful functioning; 2, > 0% to ≤25% of the time; 3, > 25% to ≤50% of the time; 4, > 50% to ≤75% of the time; and 5, >75% to ≤100% of the time. Abbreviations: ARI = aripiprazole, HAL = haloperidol, OLZ = olanzapine, RIS = risperidone, QUE = quetiapine, ZIP = ziprasidone. *HGBG, HGHJ -p < .05.
