P values from the epoch dispersion analysis. Values were calculated by dividing the number of permutation test trials with results more extreme than the true values by the total number of permutation test trials (10,000). Italics indicate values that were not statistically significant. The combination of all (6) features was significant in all patients (Pt A–E). Each patient had different trends with the individual features.

^*Highly significant (P < 1e-6).
