, , , , &
Pages 1737-1750 | Published online: 08 Nov 2013

Figures & data

Figure 1 Patients’ treatments before and during the original studies, and patient groups in the post hoc analyses. Only patients who had used OLZ or non-OLZ immediately before randomization to OLAI were included in the post hoc analyses.

Abbreviations: OLAI, olanzapine long-acting injection; OLZ, switched to OLAI from oral olanzapine monotherapy; non-OLZ, switched to OLAI from any other antipsychotic medication; N, number of patients.

Figure 2 Kaplan–Meier survival analysis of time to all-cause discontinuation from OLAI treatment. No statistically significant differences were detected in times to all-cause discontinuation in the short-term study or in the long-term study.

Figure 4 Potentially clinically significant changes in metabolic parameters after switching to OLAI treatment. The only statistically significant difference detected in potentially clinically significant changes was “weight gain” in the short-term study. Definitions: weight gain, ≥7% increase from baseline; fasting glucose, ≥7 mmol/L following baseline of <5.56 mmol/L; fasting triglycerides, ≥2.26 mmol/L following baseline of <1.69 mmol/L; total fasting cholesterol, ≥6.21 mmol/L following baseline of <5.17 mmol/L; fasting LDL, ≥4.13 mmol/L following baseline <2.58 mmol/L; fasting HDL,<1.03 mmol/L following baseline of ≥1.03 mmol/L.

Abbreviations: HDL, high-density lipoprotein; LDL, low-density lipoprotein; OLAI, olanzapine long-acting injection; OLZ, switched to OLAI from oral olanzapine monotherapy; non-OLZ, switched to OLAI from any other antipsychotic medication.

Figure 5 Potentially clinically significant changes in extrapyramidal symptoms at any time after switching to OLAI treatment. Statistically significant differences were detected in akathisia (in the short-term and long-term studies) and parkinsonism (in the long-term study).

Figure 6 Mean (SD) changes in extra pyramidal symptom scores. The only statistically significant difference was detected in the Barnes Akathisia Rating Scale in the long-term study.
