Furthermore, ROC curves showed that the capability of lnc‐KCNQ1OT1 in discriminating sepsis deaths from sepsis survivors was better than that of CRP, TNF‐α, IL‐1β, and IL‐6, but relatively weaker than the APACHE II and SOFA scores, indicating that lnc‐KCNQ1OT1 could conveniently discriminate sepsis patients with high mortality risk to some extent. This evidence concerns the gene KCNQ1OT1 and Sepsis.
