Table 7.

p-value (p) of the Wilcoxon’s signed-rank test conducted on SPLINE vs. ORIGINAL and PARABOLA vs. ORIGINAL pairs of beat-to-beat AEs, for each PPG sampling frequency (FS) and protocol phase (in this case, ORIGINAL IBIs are derived from PPG signals sampled at 256 Hz). Additionally, the effect size of each pairwise comparison (Cohen’s r) is reported.
