Partial least squares discriminant analysis (PLS-DA) of the umbilical cord plasma metabolome between the three twin comparisons, including a measure of prediction model performance (right bar graphs). The right bar graphics are leave-one-out cross-validations (LOOCV), where R2 indicates how well the model explains the data and Q2 indicates the reproducibility of the PLS-DA model. The red asterisk indicates the best classifier. List of abbreviations; MC = Monochorionic; DC = Dichorionic; L = Larger twin; S = Smaller twin
