MRI lesion status did not change interictal HFA SOZ AUC in 92 SEEG patients across six cohorts

We tested whether interictal 80–150 Hz power (high-frequency activity, HFA) separates seizure-onset-zone (SOZ) from non-SOZ bipolar pairs differently in MRI-lesional and non-lesional patients. We reused archived per-patient AUCs from an earlier AutoSci result and joined them to lesion labels in OpenNeuro participants.tsv files. The analysis included 93 patients with known lesion status and at least one SOZ and one non-SOZ pair; 92 had an HFA AUC. A stratified difference of mean HFA AUC (lesional minus non-lesional), weighted across six cohorts, was +0.004 (95% CI −0.082 to +0.090; two-sided within-cohort permutation p = 0.94). Mean AUCs were 0.632 and 0.636. The confidence interval lies within ±0.10 AUC, excluding a difference larger than about 0.09 in either direction under this analysis. Restricting to strata with at least three patients per group gave +0.005 (p = 0.93). Secondary feature differences were not significant after Holm correction. Lesion definitions differed by center, some groups were small, SOZ labels were clinical, and the result cannot separate marker quality from label quality.

usesArchived SEEG cohorts show that SOZ-marker sample sizes depend on the feature comparison
Its 57 vs 35 lesional/non-lesional design is an example; our minimum detectable difference for this size is 0.12 AUC, so its null excludes only large differences.
