(a through d) Multiple comparisons of different studying groups for sign_mdetr. KW mean ranks and confidence intervals depicted here, for sign_mdetr. Multiscale entropy (sumEn) of the whole signal, continuous wavelet entropy (cwtEnrto) for the whole signal and for scale 3, and finally, wavelet entropy per scale 4 (WEn(s4)) exhibited significant differences between different groups of patients.
