Table 5 Efficacy of computed tomography subjective signs to predict Irreversible transmural intestinal necrosis

CT signs	AUC (95%CI)	P value	Sensitivity (95%CI)	Specificity (95%CI)
Reduced or absent bowel wall enhancement	0.681 (0.581-0.769)	0.002	91.67 (80.0-97.7)	44.44 (30.9-58.6)
Bowel dilation	0.753 (0.658-0.833)	< 0.001	72.92 (58.2-84.7)	77.78 (64.4-88.0)
Parenchymatous organ infarction	0.615 (0.513-0.709)	0.046	56.26 (41.2-70.5)	66.67 (52.5-78.9)
Combination signs	0.853 (0.769-0.915)	< 0.001	93.75 (82.8-98.7)	64.81 (50.6-77.3)

The difference between the two groups marked with the same letter is not statistically significant, and the difference between the two groups marked with different letters is statistically significant. CT: Computed tomography; CI: Confidence interval; AUC: Area under the curve.
