Table 3 Confidence level of misclassified genetically confirmed 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)
15_Av (52%) 254 (56%)
84_Av (99%) 297 (59%)
  333 (100%)
  342 (74%)
  371 (85%)
  1. Confidence levels were calculated by the Pattern Expert Airspect program after ANN and cross validation analysis with blood donor samples and genetically confirmed HHT patient samples for spectral regions 3.150 - 2.750 cm-1 and 1.850 - 750 cm-1.
