Twenty-seven biologically relevant volatile organic compounds in rat odour.

Given are retention times (RT), mean relative abundance (a compound’s peak area in chromatographic profile) for hungry and satiated rats, the mean difference in abundance, and test statistics for each compound using 5,000 permutations and Bonferroni correction for multiple testing. Substances that differed significantly in their abundance between hungry and satiated rats are marked in grey. Formally identified compounds are marked in bold.
