Association between urine metabolite and change in vascular function

Metabolite	Dependent Variable	Model	Unstandardized Slope, Change (95% CI)	Standardized Slope, Change	P Value
Serine	∆FMD_BA	Unadjusted	1.51E³ (6.06E² to 2.41E³)	0.69	0.003
		1	1.59E³ (47.64 to 3.13E³)	0.73	0.04

Metabolite was entered as the area normalized to urinary creatinine and the internal standard (methionine-d₃). Model 1 was adjusted for age, sex, and systolic BP. 95% CI, 95% confidence interval; FMD_BA, brachial artery flow-mediated dilation.
