Progesterone-associated arginine decline at luteal phase of menstrual cycle and associations with related amino acids and nuclear factor kB activation
Fig 2
Plasma concentrations of arginine, ornithine and citrulline shown as box-and-whisker blots at early (T1) and late (T2) follicular and mid (T3) and late (T4) luteal phase across a given menstrual cycle in 28 women.
Results were obtained by repeated measures ANOVA and Holm-Sidak all pairwise multiple comparison procedures; same superscripts indicate significant differences (P < 0.01) between time points.
