(a, b) Comparison of 890 nm excitation fluorescence intensity spectra respectively for Control and Metastasis groups and for Control and each metastasis origin organ groups. (c, d) Histograms of molecular contributions respectively for Control and Metastasis groups and for Control and each metastasis origin organ groups. (e, f, g) 3D histograms, presented in inverse log-scale, of the calculated P-values through a t-test for all 1 by1 group (Control, Skin, Lung, Endocrine system, Breast metastasis) comparisons (90% C.L. and tail = 2), respectively for the FAD, Lipopigments and Porphyrin molecules.
