Classification statistics.

<p><b>(</b>A) Number of days with CA above chance level; (B) number of delivered sentences with CA above chance level; (C) maximum chance-level upper limit, calculated using the metric described in BCI effectiveness metric section; and (D) mean and standard deviation of CA above chance level, obtained using the <i>f</i>NIRS, EEG, and EOG signal data for patients F, G, B, and W. For the training sessions, the CA is reported for <i>f</i>NIRS, EEG, and EOG signals. For feedback and open question sessions, CA is only reported for the <i>f</i>NIRS signal because the feedback was provided using only the <i>f</i>NIRS signal as a result of superior CA of the <i>f</i>NIRS signal during the training sessions as compared to EEG and EOG signals.
