Establishment of a pattern recognition metabolomics model for the diagnosis of hepatocellular carcinoma

Figure 3 Metabolic profiles of serum from hepatocellular carcinoma patients, cirrhosis patients and healthy controls. A: The orthogonal partial least squares discriminant analysis (OPLS-DA) score plot for all the three groups. Model efficiency: R2X = 0.370 cum, R2Y = 0.838 cum, Q2 = 0.467 cum; B: The OPLS-DA score plot of C group and N group. R2X = 0.187 cum, R2Y = 0.790 cum, Q2 = 0.603 cum; C: The OPLS-DA score plot of Y group and N group. R2X = 0.559 cum, R2Y = 0.962 cum, Q2 = 0.696 cum; and D: The OPLS-DA score plot of C group and Y group. R2X = 0.274 cum, R2Y = 0.812 cum, Q2 = 0.358 cum. OPLS-DA: Orthogonal partial least squares discriminant analysis.
