Similarly, asthma was also not associated with the clinical traits or cytokines that were positively [blood neutrophil counts, lactate, CRP, d-dimer, OpenSAFELY (OS) score, IL-6, S100A9, CCL20, TF, CXCL10, GM-CSF, IL-15, TREM-1] or negatively (blood lymphocyte counts, haemoglobin, bicarbonate and SaO2/FiO2) correlated with mortality. This evidence concerns the gene CCL20 and asthma.
