Extended Data Fig. 6: Proportion of metabolite variance explained by eGFR.

The proportion of a metabolite’s variance explained by eGFR is represented on the x-axis. All metabolites quantified from plasma and urine are shown along the y-axis, ordered by the maximum variance explained across plasma (red color) and urine (blue color). The metabolite with the largest amount of variance explained by eGFR was plasma creatinine.
