Multifractal-Multiscale Analysis of Cardiovascular Signals: A DFA-Based Characterization of Blood Pressure and Heart-Rate Complexity by Gender

Figure 5

Comparison of among cardiovascular signals at different q values. (a) Mean ± standard error of the mean over the group () as function of τ. (b), from top to bottom: statistics of Wilcoxon’s tests at each scale τ for comparing IBI and SBP, IBI and DBP, and SBP and DBP. Dashed horizontal lines represent the 5% threshold of statistical significance; values above the threshold are marked by a red dot and indicate statistically significant differences at .
