¹𝑃 value calculated with the Wilcoxon test; values lower than 0.05 suggest statistical relevance.
²𝑃 value calculated with the Anderson-Darling test, values lower than 0.05 suggest statistical relevance.
³Average area of peaks for colorectal cancer subjects.
⁴Average area of peaks for health subjects.
⁵Standard deviation of peaks for colorectal cancer subjects.
⁶Standard deviation of peaks for health subjects.
