Fig. 3.

Illustration of the Fisher’s $z$-transformed Spearman correlation (COR) results including all three data types (columns: SIM, ME, and MI) of (a) $\mathrm{\Delta }[\mathrm{HbO}]$ and (b) $\mathrm{\Delta }[\mathrm{HbR}]$. Circles represent mean COR values and error bars represent standard error of the mean across participants. Below each subfigure statistical results are displayed by color coded stars representing Bayes factors ${\mathrm{BF}}_{10}>3$ which indicate evidence favoring the alternative hypothesis $H_1$, i.e., that there are differences between two correction methods. For details of statistical results including ${\mathrm{BF}}_{10}<3$, see Tables S7–S12 in the Supplementary Material.
