Prognostically, low levels of GAS6 at the time of hospital admission and/or before antiinflammatory treatment were predictive of low risk for ICU transfer (Figure 3F); for example, 6.5% of COVID-19 patients with GAS6 < 24 ng/mL required transfer to ICU compared with 44.4% of those with GAS6 ≥ 24 ng/mL (Figure 3, G and H). This evidence concerns the gene GAS6 and COVID-19.
