Association of Lateralized Interictal Epileptiform Discharges with Postsurgical Seizure Outcomes in Patients with Tuberous Sclerosis Complex: A 10-Year Retrospective Study at a Single Center

Table 5

The relationship between IED patterns and number of tubers in TSC patients.

IED patterns	Number of tubers	Number of epileptogenic tubers	Ratio of epileptogenic tubers
Focal	4.22 (1-7)	1.56 (1-2)	0.37 (0.25-1)
Lateralized	5.03 (2-8)	1.61 (1-3)^a	0.32 (0.20-0.67)
Multifocal	5.29 (2-8)	1.93 (1-4)	0.36 (0.14-0.67)
Generalized	5.11 (2-9)	2.11 (1-4)	0.41 (0.20-0.67)

Abbreviations: IEDs: interictal epileptiform discharges; TSC: tuberous sclerosis complex. Values are mean (range). ^a, the number of epitubers in the focal group versus the data in the generalized group.
