While GM-CSF was mostly undetected in both in healthy individuals and COVID–19 patients, ICU admission levels of G-CSF and IL-7 were significantly higher in COVID–19 patients than in healthy individuals (Figures 8A, B; p=0.0002 and p<0.0001 for G-CSF and IL-7, respectively). The gene discussed is CSF3; the disease is COVID-19.
