RESULTS	For time to treatment failure , we identified several significant risk factors : sex ( male vs female , hazard ratio [ HR ] 086 , 95 % CI 075-099 ) , treatment history ( taking non-SANAD antiepileptic drugs [ other than those listed above ] vs treatment naive , 127 , 105-153 ) , age ( eg , older than 71 years vs 10 years or younger , 068 , 051-091 ) , total number of seizures ( eg , four to 11 seizures vs two or fewer , 108 , 105-111 ) , electroencephalogram results ( epileptiform abnormality vs normal , 126 , 107-150 ) , seizure type ( eg , secondary generalised vs simple or complex partial only , 078 , 066-091 ) , site of onset ( not localised vs temporal lobe , 125 , 106-147 ) , and treatment ( lamotrigine vs carbamazepine , 076 , 061-095 ) .\
