Extracted (a) absorption coefficients (${\mu }_a$) at 665 nm, (b) reduced scattering coefficients (${\mu }_s^{\prime }$) at 665 nm, and (c) oxygen saturation (${\mathrm{SO}}_2$) for all subjects for pre-MB and post-MB conditions. Note that (a) is on a log scale, and (b) and (c) are on linear scales.
