Mean ± SE postabsorptive whole-body Arg clearance (A) and NO production (conversion of Arg to citrulline) (B) in healthy controls (n = 19) and COPD patients (n = 23). Statistics were obtained by using 2-factor repeated-measures ANOVA with “group” and “day” used to compare differences between groups and test days. A significant group effect was found for Arg clearance, but no significant day effect or interaction. For NO production, only a significant interaction between group and day was observed (P = 0.0325; Supplemental Figure 5). Data are shown as the mean value of both days. ****Different from controls, P < 0.0001. COPD, chronic obstructive pulmonary disease; FFM, fat-free mass; NO, nitric oxide.
