From: Intraoperative discrimination of native meningioma and dura mater by Raman spectroscopy
Top: Average spectra of all normalized (z-score normalized) meningioma and dura mater measurements; Bottom: Absolute difference spectrum of the previously plotted average spectra. Significant differences, calculated using Wilcoxon-Mann–Whitney-U test (Bonferroni-corrected p-value, resulting in p ≤ 0.01/1603 = 10 − 6), are highlighted in yellow.
