Figure 6: Receiver operating characteristics curve (ROC) of HA and sICAM-1. For HA, AUC= 0.824; at best cut off point of >350 ng/ml could differentiate between severe (stage 3-5) from mild (stage 1-2) liver fibrosis, while for sICAM-1, AUC= 0.778; at best cut off point of >50 ng/ml could differentiate between severe (stage 3-5) from mild (stage 1-2) liver fibrosis. Pairwise comparison of ROC curves of both markers shows non-significant difference.
