Demographic information for the 21 epilepsy patients with RH language dominance who underwent RH surgery for epilepsy at the University of Washington Regional Epilepsy Center.

Group Description	Age at Mapping (years)	Age of Seizure Onset (years)	Gender (% Female)	Handedness* (% Right Handed)	Footedness* (% Right Footed)	Education (years)
All RH language dominant patients undergoing RH surgery (n =21)	X = 37.4	X = 24.1	66.6% (14/21)	28.6% (6/21)	38.1% (8/21)	X = 12.6
	SD = 13.5	SD = 17.4				SD = 2.3
	Range: 18–61	Range = 5–61				Range: 8–17
Subset of RH language dominant patients with available CSM results (n = 13)	X = 36.2	X = 21.1	61.5% (8/13)	7.7% (1/13)	23.1% (3/13)	X = 13.1
	SD = 13.40	SD = 14.6				SD = 2.7
	Range: 20–56	Range = 5–49				Range: 8–17

Note. RH = right hemisphere; CSM = cortical stimulation mapping; X = mean; SD = standard deviation. No differences were observed between the sample with available CSM data and the total sample using appropriate parametric and nonparametric tests with the exception of the results marked with asterisks.

^*The sample with available CSM data differed from the total sample on this variable at the p<.01 level.
