Table 2. Comparison of individual and combined lectins for predicting motifs.

For each of the four motifs, we calculated motif prediction scores for every glycan on the array using either a single lectin or the combination of all listed lectins. The area-under-the-curve (AUC) statistic from receiver-operator characteristic analysis indicates the degree of separation in motif prediction scores between the glycans that contain the motif and those that do not contain the motif.
