Table 2.

A list of the identified metabolites with the highest values of between-subject variability, ${\mathrm{\pi ̂}}_T^B$ (e.g. the lowest within-subject variability), among all metabolites. Rows include metabolite name, ${\mathrm{\pi ̂}}_T^B$, the equivalent value from the age and gender adjusted (A.G.A) model, the equivalent from a female-only model, p-value for the metabolite’s association with age, and p-value for the metabolite’s association with gender.
