*“Patients/Samples planned” refers to tissue samples from which the data have been collected. “Patients/Samples used” refers to the tissue samples that were found to have more than 10 fatty acid-dominated spectra (>10) through the matching algorithm and therefore contributed to the statistical analysis (see Methods).
