Figure 2

Comparisons of (a) BPW and (b) PPG harmonic indices between AD patients and control subjects: Cn, CVn, Pn, and Pn_SD. Data are mean and standard-deviation values. C5–C10 values have been multiplied by 5 to make the differences clearer. “⌢” indicates p < 0.05. In BPW indices, C3–C10, P1, and P10_SD were significantly larger and CV6, CV9, CV10, P4, and P7 were significantly smaller in AD patients than the control subjects. In PPG indices, C4, C6–C10, P2, P3, P5, and P6 were significantly larger and CV6, CV7, CV9, and CV10 were significantly smaller in AD patients than the control subjects.
