A significant trend in the association of dietary l -arginine and serum NOx, observed across quartiles of l -arginine intakes, may also consider as a dose-response effect; the trend of l -arginine-NOx association was only significant in overweight and obese compared to normal weight subjects.

There was an increasing trend in blood pressure, AIP, prevalent diabetes, HTN and CVD across increasing BMI ( p for all < 0.05). 4.
When the analysis was stratified by BMI categories, l -arginine intakes were strongly associated with serum NOx levels in overweight and obese subjects who were in the upper quartile (β = 7.6, 95% CI = 4.2, 11.0 and β = 8.1, 95% CI = 5.6, 14.0, in overweight and obese subjects, respectively); a borderline significant association was observed between l -arginine intake and serum NOx concentrations in young adults and normal weight subjects.
