Prompted by this observation, we correlated all our proteomics data with available laboratory parameters, including ELISA‐based levels of IL‐8, HNE, myeloid‐related protein‐8/14 and nucleosomes as well as the FN‐category (non‐fever, mild‐FN, complicated‐FN), binary category fever (presence or absence of fever at the time of sampling) and fever‐cause categories (including bacterial‐, fungal‐ or multifactorial‐infection, noninfectious or unknown cause). Here, CXCL8 is linked to infection.
