ROC curves of salivary metabolites in discriminating pancreatic cancer (n = 40) from control and chronic pancreatitis (n = 39). (a) N1-acetylspermine, (b) N1-acetylspermidine, and (c) spermine in short-term storage test. (d) N1-acetylspermine, (e) N1-acetylspermidine, and (f) spermine in the long-term storage test. Solid lines were original data retrieved from the previous study23. Dashed lines were generated by adding random noise. In total, 200 curves were generated with random values. ROC curves showing the top 2.5% and 97.5% AUC values are depicted.
