Table 3.

Performance level achieved, type of BCI used, mean, and range of percentage of correct responses within each BCI type. N = 49 because four patients were confronted with two and seven with three BCI types.

type of BCI	SCP	SMR	P300
number of patients	23^†	5	11
mean performance^* ± SD	66.1 ± 14.0	71.0 ± 15.8	66.0 ± 20.2
range	43 – 94	43 – 81	31 – 87
Level of succes	number of patients
chance level	5	1	0
above chance	8	-	5
criterion level	7	4	2
independence	3	-	4

as percentage of correct responses (correct response rate = CRR)

^†

N=23, because data from one patient was lost due to trainer error and for another no correct response rate was reported in the publication
