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.
