From: Using gene expression data to identify certain gastro-intestinal diseases

Method Ratioscore SVM #1* SVM #2*
Sensitivity Specificity Sensitivity Specificity Sensitivity Specificity
IBD vs. CTRL 0.94 1.00 0.97 0.94 0.99 0.97
IBS vs. CTRL 0.91 1.00 1.00 0.68 0.85 0.99
IBD vs. IBS 0.93 1.00 0.97 0.91 0.92 0.98
CD vs. UC 0.98 1.00 0.94 0.85 0.89 0.92
  1. *Training set = 80% of total, **Training set = 60% of total.
  2. Sensitivity = # true positives/(# true positives + # false negatives).
  3. Specificity = # true negatives/(# true negatives + # false positives).
