Fig. 1

The PLS-DA score plot comparing the control group to the TPOAb (+) and TgAb (+) groups. (a) PLS-DA score plot of three groups (R2X = 0.195, R2Y = 0.44, Q2 = 0.281). (b) OPLS-DA score plot comparing the Control group to the TPOAb (+) group (R2X = 0.262, R2Y = 0.756, Q2 = 0.641). (c) OPLS-DA score plot comparing the Control group to the TgAb (+) group (R2X = 0.203, R2Y = 0.56, Q2 = 0.233). The t [1] and t [2] values in the figures represent the scores of each sample in principal components 1 and 2, respectively. Each dot on the plot represents a sample in the corresponding group.
