LBR and lung cancer: When judging the types of lung cancer, the results indicated that Model LC had higher discriminatory power for differentiating lung cancer from BPD (AUC: 0.926, sensitivity: 0.837, and specificity: 0.875) than that of these single candidate lectins, such as ECA (AUC: 0.859, sensitivity: 0.894, and specificity: 0.775), RCA120 (AUC: 0.881, sensitivity: 0.772, and specificity: 0.875), HHL (AUC: 0.870, sensitivity: 0.878, and specificity: 0.750), MAL-II (AUC: 0.866, sensitivity: 0.837, and specificity: 0.825), and PHA-E+L (AUC: 0.810, sensitivity: 0.683, and specificity: 0.825).
