Figure 2From: Elevated tumor and serum levels of the hypoxia-associated protein osteopontin are associated with prognosis for soft tissue sarcoma patients Serum and tumor OPN protein levels and overall survival of STS patients. Analysis of serum (left) and tumor (right) OPN protein levels and overall survival of STS patients using a univariate Cox's proportional hazard regression model. In comparison to patients with a low serum or tumor OPN-level (dotted line), an elevated OPN-level (bold line) correlates with a 2.2- (p < 0.05) or 3.7-fold (p = 0.01) increased risk of tumor-related death for STS patients.Back to article page
