Figure 2.

Absolute (left) and creatinine-referenced (right) concentrations of 61 quantified urinary metabolites in a random subset (n = 994) of morning spot urine samples in the Northern Finland Birth Cohort 1966. The metabolites are presented in the descending order of median absolute concentrations. Several different scales are used for the x-axes to provide a clear visualization for the large concentration ranges. TMAO, trimethylamine N-oxide; HPHPA, 3-(3-hydroxyphenyl)-3-hydroxypropanoate; 2-PY, N1-methyl-2-pyridone-5-carboxamide; IS-CREA, use the creatinine concentration as the internal standard
