- Optimum ratios for the ratioscore method were from Figures 2, 3 and Additional file 3: Figure S3. CIS ➔ MS subject data were inputted and scores computed. For the SVM, 60% of controls and cases were randomly selected for the training set and 40% were used for the validation set. Sensitivity and specificity were calculated for the combined sets. These results defined the SVM. CIS ➔ MS subject data were applied to the SVM and subjects received a score of 0 if assigned to the CONTROL cohort or 1 if assigned to the CASE cohort. Sensitivity was calculated from this output.
- Sensitivity = # true positives/(# true positives + # false negatives).
- Specificity = # true negatives/(# true negatives + # false positives).
