Additionally, COVID-19 patients had a trend toward elevated levels of proinflammatory biomarkers such as Interferon γ-inducible protein 10 (IP10, median 450 vs 77.5pg/mL), interleukin 10 (IL-10, 13.6 vs 6.7pg/mL), and receptor for advanced glycation end-products (RAGE, median 3091.6 vs 720.4 pg/mL) relative to disease controls. Here, CXCL10 is linked to COVID-19.
