Figure 1. Seizure outcome at 2-year and long-term follow-up after surgery compared to controls.

Two-year and long-term (mean follow-up time 7.6 years, range 5–10) seizure situation for patients after resective epilepsy surgery compared to long-term follow-up of nonoperated controls (mean follow-up time 9.2 years, range 5–14). Seizure-free patients include those with sustained seizure freedom with or without aura since surgery (blue) and patients seizure-free at least the last year before follow-up (green).
