Additionally, the AISI score (SE = 85.58, SP = 77.78, AUC = 0.88, Y = 0.64, p < 0.0001) and CRP level (SE = 73.08, SP = 67.52, AUC = 0.74, Y = 0.41, p < 0.0001) were analyzed to SIRS, both having significant value; still, the AISI score showed to have stronger prognostic value. This evidence concerns the gene CRP and systemic inflammatory response syndrome.
