Ratios of L-arginine (lArg) (a) and homoarginine (hArg) (b) to asymmetric dimethylarginine (ADMA) in plasma samples from non-septic controls and in patients. Patients groups were compared using the non-parametric Kruskal-Wallis test for trend analysis between patients with surgical trauma (Surg), sepsis and septic shock (25 controls, 20 patients with surgical trauma, 63 patients with sepsis, and 17 patients with shock). Data are presented as median with interquartile range. Circles represent ratios of individual subjects. ns non-significant
