Figure 4. Effect of olanzapine on plasma fasting free fatty acids.

Baseline blood samples were collected approximately 10–12 h following the final dose of olanzapine or placebo tablets prior to beginning an oral glucose tolerance test for hormone and metabolite analyses. Plasma free fatty acid concentrations were measured for all subjects under placebo- and olanzapine-treated conditions. Data are expressed as a box plot for placebo and olanzapine-treated groups. An asterisk indicates (P = 0.016) a significant difference between the medians of the placebo and olanzapine groups (n = 15).
