Characteristics of glucose change in diabetes mellitus generalized through continuous wavelet transform processing: A preliminary study

Figure 2 Comparison of the three-dimensional scattering diagram between groups. The x-axis indicates time during a day; the y-axis indicates the area enclosed at the 0.02625 scalogram value; the z-axis indicates a pseudo-frequency determined after continuous wavelet transform processing. The wave cycles of P1 signals belonging to type 1 diabetes mellitus (T1DM) were distributed during 17-24 min. The loose distribution of P1 signal wave length characterized T1DM. A: Type 1 diabetes mellitus group; B: Type 2 diabetes mellitus group; C: Subjects without diabetes.
