Classification model of the subset selected based on analytical data, including sample predictions. OPLS-DA predictive score plot showing separation between pre- exercise (black circles) and post- exercise (gray circles) serum samples with a cross-validated classification accuracy of 93.8% (Class prediction (CV)). Predictively classified test samples (remaining samples from test occasion one and two), marked as open circles, display high predictive classification accuracy (Class Prediction (Test set): 96.1%) for pre- exercise samples (black open circles) and post- exercise samples (gray open circles).
