Figure 2

Error bars represent 95% confidence intervals (CI). The Odds Ratio (OR) is odds of uncontrolled seizures after an AED switch. OR >1 suggests poor control for generic medications compared to brand name medications; OR <1 suggests lower odds of poor control for generic medications compared to brand-name medications. See Appendix for a breakdown of the number of patients who had uncontrolled seizures in the generic and brand-name groups.
