Metabolites with significantly increased abundance in murine nasopharynx vs lungs.

Spectral peaks (bins) that were significantly elevated in nasopharynx tissue, as compared to lungs, after data normalisation, are listed with their peak number. A full list of nasopharynx peak i.d.’s can be found in S2 Table. The total number of spectral/NMR peaks corresponding to each metabolite is also shown. Log2 fold-changes in nasopharynx abundance, relative to lung was calculated for n = 8 nasopharynx and n = 9 lung samples. P-values were corrected for multiple comparison by Bonferroni adjustment. Shading is proportional to the size of the fold change or of the p value.
