RTT cohort characteristics.

RTT	Age	RSSS	Seizures	Ambulation
1	3.9	7	No	No
2	5.1	13	No	Yes
3	6.9*	14	No	No
4	8.6	14	Yes	Yes

Each participant’s age (years), scores on the Rett Syndrome Severity Scale (RSSS), comorbid seizure diagnosis and ability to walk (ambulation) are listed. Note that RTT participant #3 was excluded from the main analysis due to high amplitude noise in the EEG that precluded derivation of an adequate AEP (indicated by the asterisk).
