Day–Night comparison of multifractal short- and long-term coefficients. (a) Short-term coefficients, αS(q), for IBI in Day (open circles) and Night (solid circles) periods and for −5 ≤ q ≤ +5: median ±standard error of the median over N = 14 participants; the * indicates Day vs. Night differences significant at p < 0.05; (b) long-term coefficients, αL(q), of IBI represented as in panel (a); (c) short-term coefficients of SBP and (d) long-term coefficients of SBP, represented as in panel (a); (e) short-term coefficients and (f) long-term coefficients of DBP, represented as in panel (a).
