OPLS-DA plot of ions detected by LC–MS between WBS children and the controls. (A) OPLS-DA plot in positive ion mode; (B) OPLS-DA plot in negative ion mode. Abbreviation OPLS-DA, Orthogonal Projections to Latent Structures Discriminant Analysis, OPLS-DA. Notes The PC1 and PC2 ordinates represent the scores of first and second orthogonal component score. The dot represents the each study participants with colors representing their groups. This plot shows the difference between and within groups. The more concentrated the samples within the group and the more dispersed between the groups indicate the separation is more reliable.
