From: In situ brain tumor detection using a Raman spectroscopy system—results of a multicenter study
(A–D) Box and whisker plots associated with the five most important bands selected by machine learning to distinguish non-tumoral brain from tumor: (A) non-tumoral brain vs. glioblastoma, B) non-tumoral brain vs. metastases, (B) non-tumoral brain vs. meningioma, (C) non-tumoral brain vs. tumors (glioblastoma, metastases and meningioma measurements lumped together). P-values for all bands on all plots are p < 1e−4 except for the 1659 cm−1 band which had p > 0.05 (p = 0.15).
