CRP and abscess: When comparing the analysis of the AISI score (SE = 82.93, SP = 81.63, AUC = 0.90, Y = 0.65, p = 0.0001) and CRP levels (SE = 70.73, SP = 72.45, AUC = 0.78, Y = 0.43, p = 0.0001), it is clear that AISI score has significant prognostic value in predicting the seriousness of an abscess (Figure 4).
