(a, b) Comparison of 810 nm excitation fluorescence intensity spectra respectively for Control and Metastasis groups and for Control and each metastasis origin organ groups (c, f) Box plots comparing respectively Redox ratio and Optical Index ratio of Control vs. global metastasis group. (d, g) and for Control and metastasis sub-groups. (e, h) 3D histograms, presented in inverse log-scale, of the calculated P-values through a t-test for all 1 by 1 groups (Control, Skin, Lung, Endocrine system, Breast metastasis) comparing (95% C.L. and tail = 2), respectively for Redox ratio and Optical Index ratio.
