COMP and breast angiosarcoma: Spearman’s rho correlation analysis demonstrated that circulating COMP levels were positively correlated with liver stiffness (r = 0.54, P < 0.001), AST (r = 0.45, P < 0.001), ALT (r = 0.35, P < 0.001), ALP (r = 0.32, P < 0.001), TB (r = 0.44, P < 0.001), and DB (r = 0.41, P < 0.001) in BA patients.
