Cognitive and clinical correlations between significant TEP amplitude changes and clinical/cognitive measures in patients with schizophrenia A highly significant correlation between TEP P60 amplitude change induced by SICI and the longest span of the Letter-Number Span Test (r = −0.775, p = 0.003, N = 12; α = 0.05/5; controlled by the number of cognitive/clinical measures) (see Fig. 6(A) ) was observed in patients, while no other relationship was uncovered for measures of IQ or executive functioning.
