The area under the curve (AUC) of IG percentage to predict SBI was 0.83 with 95% confidence interval (CI) [0.78\u20100.88]; WBC was 0.76 (95% CI 0.70\u20100.83); ANC was 0.73 (95% CI 0.67\u20100.80), and CRP was 0.79 (95% CI 0.73\u20100.85). When infection markers were compared to the most appropriate cut\u2010off values in predicting SBI, IG percentage showed the highest sensitivity and specificity.
