Table 6 Prediction value of age, uric acid, interleukin-6, and hemoglobin histogram prediction model

Predictive index	AUC	Optimum cutoff value	Sensitivity	Specificity	95%CI	P value
Age	0.663	0.471	0.500	0.883	0.499-0.827	0.061
UA	0.657	0.396	0.556	0.883	0.482-0.833	0.070
IL-6	0.744	0.570	0.611	1.000	0.582-0.907	0.005
Hb	0.632	0.373	0.611	0.667	0.463-0.802	0.128
Age + UA + IL-6 + Hb	0.939	0.432	0.889	0.867	0.875-1.000	< 0.001

UA: Uric acid; IL-6: Interleukin-6; Hb: Hemoglobin; AUC: Area under the receiver operating characteristic curve; OR: Odds ratio; 95%CI: 95% confidence interval.
