Multivariable regression analysis of plasma l-arginine concentrations in 1141 healthy individuals from the Framingham Offspring Cohort

Variable1	β ± SE2	P value
Glomerular filtration rate	0.05 ± 0.03	0.044
Fasting glucose	0.20 ± 0.06	0.002

¹Candidate variables that were considered for model entry were age, sex, BMI, SBP, DBP, the total-:HDL cholesterol ratio, alcohol consumption, TG, glomerular filtration rate, homocysteine, fasting glucose, and CRP. CRP, C-reactive protein; DBP, diastolic blood pressure; SBP, systolic blood pressure.

²All regression coefficients (β estimates) represent the estimated mean change in l-arginine ( mol/L) per 1-unit increase in the corresponding covariate.
