${}^{a}p<$0.1, ${}^{A}p<$0.05, ${}^{\mathbf{A}}p<$0.01 for comparison of means unpaired sample Wave versus Re-sample; ${}^{d}p<$0.1, ${}^{D}p<$0.05, ${}^{\mathbf{D}}p<$0.01 for comparison of means paired Re-sample versus Baseline. For unpaired sample comparisons, two-tailed Wilcoxon rank-sum tests. For paired sample comparisons, two-tailed Wilcoxon signed-rank tests.
