CRP and appendicitis: In addition, our results also revealed that only CRP (t = −3.475, P = 0.002) and sB7H3 (t = −2.309, P = 0.023) were statistically different between the nonperforated appendicitis group and the perforated appendicitis group, with corresponding AUROC values of 0.734 (cutoff value of CRP = 67.005 mg/L) and 0.675 (cutoff value of sB7H3 = 48.033 ng/mL), respectively.
