There were significant differences in the levels of IL-6 (Figure 4K), IL-5 (Figure 4M), IL-12p70 (Figure 4N), and IL-17 (Figure 4O) between each two of the groups, and they were highest in pSS-ILD patients while lowest in the healthy controls (p < 0.05). The gene discussed is IL17A; the disease is interstitial lung disease.
