MGP and aortic valve disorder: Based on the Pearson correlation analysis, Fetuin-A and Lp(a) were positively correlated with severity of degenerative calcified aortic valve disease (r=0.083 and 0.129; P=0.266 and -0.085, respectively), while MGP and macrophage density were negatively correlated with it (r= -0.718 and -0.132, respectively; both P<0.001) (Fig. 2).
