Figure 3
The sample entropy over different time scales. (A) The red square open symbols represented the entropy of patients with DRE before VNS, and the light blue open circles the entropy of healthy control subjects. (B) The dark blue solid squares represented the entropy of Responders0 before VNS, and the green open squares the entropy of Non-responders0 before VNS treatment. Symbols represent the mean values of entropy for each group and bars represent the standard error (\({\rm{SE}}=\mathrm{SD}/\sqrt{n}\), where n is the number of subjects). *p < 0.05, **p < 0.01, and ***p < 0.001 for comparison between the responders0 and non-responders0.
