Likewise we found a highly significant dose-dependent effect across all treatments for the rate of adverse events leading to discontinuation ( p < 0.0001), yet a nonsignificant (retigabine, lacosamide) or small (eslicarbazepine; p = 0.0276) impact of dose variation on the rate of seizure freedom (most likely due to limitations of rare event analysis).
