A non-parametric Mann-Whitney-U test was used to compare for significant differences in metabolite concentrations between two general tumour types. This was repeated for all binary comparisons of the tumour groups with a significance level of p < 0.01. Significantly higher tumours are listed by abbreviation. Higher significance levels are indicated with asterisks * = p ≤ 0.005, ** = p ≤ 0.001.
