Table 4.
Differences between the three groups of patients with respect to the nonparametric Kruskal-Wallis (KW) test and analysis of multiple groups
| Features | P values |
|---|---|
| Sign_m | |
| WEn(s4) | 0.0591 (marginally) |
| WEn(s8) | 0.0242 |
| Sign_mdetr | |
| sumEn | 0.0314 |
| WEn(s4) | 0.0535 |
| WEn(s5) | 0.065 (marginally) |
| WEn(s6) | 0.0592 (marginally) |
| WEn(s8) | 0.0242 |
| CWTentro | 0.0446 |
| CWTentro 3 (metabolic) | 0.0479 |
The table shows, for sign_m and sign_mdetr signal, the statistically significant differences for the three groups, according to the KW test. Wen, wavelet entropy; CWTentro, entropy of the whole signal transformed with continuous wavelet transformation; sumEn, multiscale entropy.
