LYZ and interstitial lung disease: In contrast, the levels of IL-10 in BAL were decreased in F-ILD when compared to those in NF-ILD patients (9.80 ± 0.43 vs. 15.2 ± 1.30 pg/mL, p < 0.001, respectively) (Figure 3D) and correlated with SLPI (r = 0.44, p < 0.001) (Figure 3E) but not with lysozyme levels in the BAL of ILD patients (Figure 3F).
