Effective immune-inflammation index for ulcerative colitis and activity assessments

Table 3 Receiver operating characteristic analyses of systemic immune-inflammation index, neutrophil-lymphocyte ratio and platelet-lymphocyte ratio in diagnosing ulcerative colitis

Variable	Cut-off	AUC (95%CI)	Sensitivity, %	Specificity, %	P value
SII	> 562.22	0.856 (0.814-0.891)	79.65	76.16	< 0.001
NLR	> 2.66	0.858 (0.817-0.893)	75.00	82.56	< 0.001
PLR	> 156.54	0.754 (0.705-0.799)	65.70	76.16	< 0.001

AUC: Area under the receiver operating characteristic curve; CI: Confidence interval; NLR: Neutrophil-lymphocyte ratio; PLR: Platelet-lymphocyte ratio; SII: Systemic immune-inflammation index.
