Figure 5. Box plots of the glutamate normalized signals identified by ANOVA analysis.

Box plots of ${\xi }_{metabolite,glutamate}^{Celltype}$ for those 16 metabolites that were identified by an ANOVA analysis that indicated $〈{\xi }_{metabolite,glutamate}〉$ was unequal between at least two of the four cell types. While the ANOVA analysis identified both $〈{\xi }_{CP,glutamate}〉$ and $〈{\xi }_{glutamine,glutamate}〉$, post-hoc/multiple comparison testing could not identify any significant differences in either $〈{\xi }_{CP,glutamate}〉$and $〈{\xi }_{glutamine,glutamate}〉$ between the cell lines, which is denoted by the superscript ‘##’.
