3. Figure 2
Heat map of 35 qPCR verified genes (23 up-regulated and 12 down-regulated) based on the microarray data. Hierarchical clustering and gene function enrichment were performed using Euclidean distance metric and centroid linkage method (unsupervised clustering). Pancreatic cancer patients (n = 12) and healthy controls (n = 12) could be classified into distinct groups, indicating the discriminatory power of salivary mRNA biomarkers. The GEO database access number of all microarray experiments is GSE14245.

4. Figure 3
ROC curve and interactive dot diagram for the logistic regression model. (A) The logistic regression model using 4 biomarkers (KRAS, MBD3L2, ACRV1, and DPM1) yielded an AUC value of (cutoff, 0.433). (B) Interactive dot diagram was based on the qPCR data of the noncancer group (n = 60) and cancer group (n = 30).
