ARG2 values were statistically increased in non-asthmatic patients with chronic rhinosinusitis compared to the control group (FR 2.42 ± 0.57 vs. 1.31 ± 0.21, p = 0.028), while in asthmatic patients with chronic rhinosinusitis, although high ARG2 levels were observed (FR 1.78 ± 0.5), these were not significantly increased compared to the control group (Figure 5). This evidence concerns the gene ARG2 and chronic rhinosinusitis.
