In the original publication of the article:

1. The affiliation of Kamen Ivanov was inaccurate. The correct affiliation of Kamen Ivanov is given below:

²Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences, The Shenzhen Key Laboratory for Low-cost Healthcare, 1068 Xueyuan Avenue, Shenzhen University Town, Shenzhen, 518055 People's Republic of China

³Shenzhen College of Advanced Technology, University of Chinese Academy of Sciences, 1068 Xueyuan Avenue, Shenzhen University Town, Shenzhen, 518055 People's Republic of China

2. In equation (3) the nominator and denominator were exchanged. The correct form of the equation is given below:

$$\mathit{\text{SamEn}}\left(X_N,m,r\right)=-ln\frac{\Phi \left(m+1,r\right)}{\Phi \left(m,r\right)}$$ 3

Authors confirm that the mistake in the equation is only a typo, while in all analyses, sample entropy was calculated correctly; hence all presented results and discussions in the original study remain valid.

Authors apologize to the readers of Medical & Biological Engineering & Computing for any inconvenience caused due to the inaccuracies described above.
