Table 3.

Odds of seizure-freedom 6 months after index date, after controlling for covariates, among various subgroups relative to seizure status at index date (seizure-free or not seizure-free), whether or not AED was switched (case vs. control), and number of AEDs failed.

Comparison Odds Ratio 95% CI p-value
All subjects, seizure-free vs. non-seizure-free at index date 3.34 0.54 – 22.90 0.202
Non-seizure-free patients, controls vs. cases 1.66 0.36 – 8.42 0.523
 Non-seizure-free patients, per previous AED failure 0.61 0.37 – 0.91 0.032
Seizure-free patients, controls vs. cases 6.53 1.02 – 61.19 0.060
 Seizure-free patients, per previous AED failure 0.85 0.57 – 1.39 0.469
