A: bar graphs showing the Spearman correlations for morphology features and time to next seizure (left) and time from previous seizure (right). *Statistically significant correlations (α = 0.05). B: Repeat analysis when overlapping HFOs are removed. Patients B and C had none so the analysis was unchanged (italics). Black circles indicate subtle differences from A, most notably that 2 values in patients A and D become significant (P < 0.05). Kruskal Wallis tests all remained P < 0.001 when overlappers were removed (not shown).
