As shown in Figure 2, IL‐6 [216.79 (71.86–467.94) pg/mL versus 43.92 (19.39–85.13) pg/mL], IL‐10 [6.27 (1.25–15.53) pg/mL versus 1.25 (1.25–1.72) pg/mL], TNF‐α [9.37 (1.25–27.26) pg/mL versus 1.25 (1.25–3.71) pg/mL], and IFN‐γ [7.33 (2.32–30.48) pg/mL versus 1.96 (1.25–9.35) pg/mL] levels in the BALF of the Fever MPP group increased significantly as compared to that in the Non‐fever MPP group (all p < .05). This evidence concerns the gene IFNG and Fever.
