Fig 4. Correlations between the classification confidence (MEG-based measures) and self-reported clinical scores.

(A) severity; and (B) symptoms for mTBI patients. The higher confidence that a given subject is classified as having mTBI, the higher the corresponding clinical scores. The correlations are shown as functions of the number of best features extracted from alpha connectivity and ranked before training. Scatter plots between classification confidence and clinical scores are shown at specific thresholds: k = 11 and k = 33 for (C) severity score; and (D) symptoms scores, respectively.
