Therate of MCM was 3.5% for no AED, 3.7% for all monotherapy outcomes<strong>and</strong> 6.0% for polytherapy outcomes, which was significantly worse. Only 3drugs had large enough numbers to compare monotherapy outcomes; carbamazep<strong>in</strong>e900, valproate 715 <strong>and</strong> lamotrig<strong>in</strong>e 647. The next largest wasphenyto<strong>in</strong> with 82 <strong>and</strong> the others were very much “also ran”. MCM rate was2.2% for carbamazep<strong>in</strong>e, 6.2% for valproate (P
