Multivariable Exact Logistic Regression Analyses of Risk Factors for Uncontrolled Seizures and Seizure After Antiseizure Drug Withdrawal.

Variable	P Value	Odds Ratio (95% CI)
Uncontrolled seizures
Gender (male vs female)	.02	0.18 (0.04, 0.77)
Gabapentin vs other AED	.06	0.16 (0.02, l.ll)
Seizure control with first AED vs no control	.08	0.26 (0.06, 1.15)
Longer vs short interval from DX to first seizure	.09	l.02 (0.99, l.04)
Intractable seizures
Age ≤3 vs >3 years at cancer diagnosis	.01	9.6 (l.6, 56.8)
CNS leukemia at diagnosis vs normal CNS	.02	0.l (0.02, 0.69)
Seizure relapse after AED withdrawal
Seizure control with first AED vs no control	.04	−2.7 (−5.2, −0.2)
Focal neurologic deficit present vs absent	.08	3.1 (−0.3, 6.4)
Radiation treatment vs no treatment	.05	2.5 (−0.3, 5.3)
