For example, plasma CXCL10 was identified as a key predictor for ICU transfer and mortality in COVID-19 patients, with an AUC of 0.8374 when combined with the neutrophil-to-lymphocyte ratio (NLR) and time from symptom onset and with an AUC of 0.7334 when used alone to predict death [46]. The gene discussed is CXCL10; the disease is COVID-19.
