Nitric oxide in acne vulgaris (AVS). (A) Levels of nitric oxide in the sera of AVS patients with mild (n = 20), moderate (n = 23), and those with severe (n = 7) scores and in normal human sera (NHS, n = 40). *P < 0.05 vs. NHS; # P < 0.05 vs. mild AVS; ## P < 0.05 vs. severe AVS. (B) Levels of nitric oxide in the sera of all studied AVS patients (n = 50) and NHS (n = 40). @ P < 0.01 vs. NHS. Each bar shows the mean ± SEM. Comparison analysis was performed using one‐way ANOVA followed by Tukey's post hoc test.
