Novel Application of a Multiscale Entropy Index as a Sensitive Tool for Detecting Subtle Vascular Abnormalities in the Aged and Diabetic

Figure 3

Changes in sample entropy ( ) with different scale factors in the four groups of subjects. Symbols represent the mean values of entropy for each group, and bars represent the standard error ( ), where is the number of subjects. Group 1: healthy young subjects; group 2: healthy middle-aged or elderly subjects; group 3: well-controlled diabetic subjects; group 4: poorly controlled diabetic subjects.
