The use of the selected LncRNA and IL11RA mRNA in assessing the severity of infection was made efficient using ROC curve analysis, with the ideal cutoff values of 15.95 for IL11RA mRNA (AUC = 0.803) and 40.5 for LncRNA RP11-773H22.4 (AUC = 0.777). This evidence concerns the gene IL11RA and infection.
