HbR at the supine position showed a significance-approaching covariation with EEG vigilance ( r = −0.36, p = 0.1) and HbO at the sitting position also approached significance ( r = –0.34, p = 0.1).
HbR at the supine position showed a significance-approaching covariation with EEG vigilance ( r = −0.36, p = 0.1) and HbO at the sitting position also approached significance ( r = –0.34, p = 0.1).
However, at other positions, the covariation did not reach significance after multiple comparison correction, although a negative trend in the association was consistently noted.
