Table 5 Confidence level of misclassified HHT patients after analysis of both spectral regions

From: HHT diagnosis by Mid-infrared spectroscopy and artificial neural network analysis

Non-HHT samples classified into the HHT group (false positive) HHT patient samples classified into the control group (false negative)
3_Av (65%) 287 (78%)
15_Av (73%) 297 (80%)
84_Av (99%) 300 (84%)
95_Av (74%) 324 (57%)
162 (99%) 325 (70%)
214 (78%) 330 (83,5%)
214a (69%) 333 (100%)
306 (82,5%) 348 (99%)
334 (88%) 350 (93%)
358 (100%) 356 (97%)
  1. Confidence levels were calculated by the Pattern Expert Airspect program after ANN and cross validation analysis with all HHT samples and all control samples for spectral regions 3.150 - 2.750 cm-1 and 1.850 - 750 cm-1.
