Figure 1.

Breakdown of aberrant results by location. The percentage of aberrant cases for community clinic (dark blue bars), primary care (medium dark blue bars), oncology (medium light blue bars), and pain management (light blue bars) is depicted. The overall aberrant cases are broken down by location into 4 categories (simulated compliance, illicit use, not taking prescribed medication, taking medication not prescribed) and the percentage of cases in each category is depicted. Some cases may have results in more than one category. Results that differ significantly by location are shown with a * (p < 0.05) and ** (p < 0.001).
