ECT parameters associated with percentage volume expansion in the right MTL.

	B	SE	β	p-value
Total EEG seizure duration	0.01	0.006	0.39	0.039
Electric field	0.11	0.09	0.24	0.20
Number of ECTs (residuals)*	0.38	0.38	0.18	0.33

B: non-standardized coefficient; SE: standard error; β: standardized coefficient.

^*The number of ECTs (residuals) is the information about the number of ECTs that is not explained by the total EEG seizure duration, hence due to the high correlation (r = 0.68, p < 0.001) all information about the number of ECTs is included in this regression model.
