Figure 2

Comparison (BP vs. SASLEFT (a), BP vs. HbO2 (b) and SASLEFT vs. HbO2 (c)) of medians (thick lines) of the time-averaged wavelet transforms of signals recorded in all 30 subjects: BP (red line), SASLEFT (blue line) and HbO2 (violet line) obtained from 30 min recordings. Shaded areas indicate the inter-quartile range (25th, 75th percentiles). *p < 0.05; **p < 0.01; ***p < 0.001.
