The clinical decision curve for sepsis in infected patients demonstrated that when the threshold probability of IL-10 detection alone was 8%-100%, the threshold probability of IL-17 detection alone was 6%-93 %, the threshold probability of PCT detection alone was 6%-100 %, and the probability of the three combined detection thresholds was 1%-100 %, the predictive model's net clinical benefit was significant. This evidence concerns the gene IL17A and Sepsis.
