Association of L-arginine and L-arginine derivates with all-cause or cause-specific mortality.

HR = hazard ratio; CI = confidence interval. ADMA = asymmetric dimethylarginine; SDMA = symmetric dimethylarginine. L-Arginine and L-arginine derivates levels were categorized into three levels according to the age- and sex-specific 33th and 66th percentile (for more detail see supplement). * Subjects with L-arginine levels upper limit of quantification were excluded. †Model was adjusted for sex, physical activity, smoking and waist circumference. Age was used as timescale.
