Figure 5From: Proteomics-based identification of haptoglobin as a favourable serum biomarker for predicting long-term response to splenectomy in patients with primary immune thrombocytopeniaReceiver operating characteristic (ROC) curve for the preoperative serum level of Hp in responders versus nonresponders. The area under curve (AUC) value of the comparison between groups was 0.867 (95% CI: 0.764-0.970). The optimal cutoff value of preoperative serum Hp levels (1173.80 μg/ml) derived from the ROC curve led to 78.4% sensitivity and 84.6% specificity.Back to article page
