LFQ levels of five proteins (CRP, SAA1, SAA2, PIGR, and FGL1) were significantly more abundant and levels of PZP and immunoglobulin heavy chain variable region 26 (IGHV‐26) were significantly decreased in the fever sample group compared with the non‐fever sample group, which is consistent with the correlation analysis (Figure 2D and Table S8). This evidence concerns the gene PZP and Fever.
