Additionally, the multivariate analysis revealed that LncRNA RP11-773H22.4, hsa-miR-4257, IL11RA mRNA, and IL11RA protein levels were independent prognostic factors besides the serum ferritin level and CT findings, encouraging the use of novel COVID-19 severity predictors along with the more routine ones (p ≤ 0.05), as shown in Table 5. The gene discussed is IL11RA; the disease is COVID-19.
