Table 6 Comparison of the efficacy of dual energy computed tomography objective indicators and computed tomography subjective signs in predicting Irreversible transmural intestinal necrosis

CT parameters	AUC (95%CI)	P value	Sensitivity (95%CI)	Specificity (95%CI)
CT_{50 KeV normal/lesion}	0.794 (0.615-0.916)	0.005	56.52 (34.5-76.8)	87.50 (67.6-97.3)
IC_{normal/lesion}	0.777 (0.596-0.904)	0.001	73.91 (51.6-89.8)	79.17 (57.8-92.9)
Combined subjective signs	0.801 (0.622-0.920)	0.006	80.95 (58.1-94.6)	72.73 (39.0-94.0)
CT_{50 KeV normal/lesion} combined with intestinal dilatation and parenchymatous organ infarction	0.857 (0.688-0.955)	0.001	95.65 (78.1-99.9)	79.17 (57.8-92.9)
IC_{normal/lesion} combined with intestinal dilatation and parenchymatous organ infarction	0.894 (0.737-0.976)	< 0.001	100 (85.2-100)	70.83 (49.8-87.4)

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; IC: Iodine concentration; CI: Confidence interval; AUC: Area under the curve.
