Plot of cross-validated probabilities and test probabilities for sample classification. (A) On x-axis individual samples: 1–5 negative controls, 6–9 samples positive at histological and LC-MS analyses; on y-axis the probability of being classified as controls (circles) or positive (rectangules). (B) On x-axis individual samples; on y-axis the probability of being classified as negative (circles, 1) or positive (rectangules, 2).
