S100A4 and hepatocellular carcinoma: According to ROC curve analysis, when Log(P) of the combined detection [Log(P)=6.350+(-1.884× TGFβI)+(-3.185×S100A4)] of TGFβI and S100A4 was <0.43, the sensitivity and specificity for diagnosing the occurrence of HCC were 71.05% and 90.79%, respectively (P<0.05, Figure 1D, Table 3).
