Table 3.

Signal-to-noise ratios (SNRs) of spectra correctly and incorrectly classified as cancer by model 1 and model 2 at confidence threshold 0.5 for training, test and validation data sets combined.

Model	Classification correctness	Number of voxels	SNR [mean±SD]	p-value^*
Model 1	correct	48	5.5 ± 2.7	0.813
Model 1	incorrect	81	5.6 ± 2.3	0.813
Model 2	correct	107	5.5 ± 2.5	0.819
Model 2	incorrect	22	5.8 ± 2.3	0.819

Mann-Whitney U test for SNR of correctly classified voxels versus incorrectly classified voxels for a given model.
