(A) Averaged effective optical density spectra of the PTG and other tissues in the 800–1050 nm range with the value subtracted at 800 nm. (B) Decomposition of the representative experimental OD spectrum into the sum of deoxyhemoglobin, water, and scattering spectra according to Eq. (3). (C) Distributions (boxplots) of the water index values for the parathyroid gland and other tissue types, (****) indicate p-value < 10− 4.
