Wavelet amplitudes of neurogenic and endothelial NO-independent activities across four phases, including the baseline phase, in groups of subjects (n = 94). These subjects were differentiated by CIVD response and the genotypes of rs73619297 of COL4A2 (a) or rs931740 of PRLR (b). Phases 1, 2, and 3 represent “vasoconstriction,” “prior to CIVD,” and “CIVD,” respectively [9]. Data are means ± standard error of the mean. a.u., arbitrary units
