Comparison of baseline-to-endpoint change in productivity level in olanzapine-treated versus haloperidol-treated first episode patients with schizophrenia. Comparison between olanzapine and haloperidol demonstrated that olanzapine was consistently associated with higher mean changes in baseline-to-endpoint productivity level for both acute phase (first 12 weeks) and long-term phase (the following 24 weeks) treatment. 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: HAL = haloperidol, OLZ = olanzapine. *HGDH-Acute, HGDH-Long-Term -p < .05.
