A refitted interval included zero for high gamma gain over contact number under patient holdout in 33 SEEG patients

We tested whether high gamma power adds seizure onset label ranking value beyond contact number within inferred electrode shafts. We used two public one-minute samples per patient from OpenNeuro ds004100, version 1.1.3. We fixed the model before fitting. Each test patient was excluded from all training. Mean within-shaft AUC was 0.782 for contact number and 0.794 for the combined model. The mean change was 0.013. A patient bootstrap refitted all models in 1,999 draws. Its 95 percent interval was -0.018 to 0.079 and included zero. The test does not establish added value for this fixed model. It does not prove that high gamma has no added value. The package preserves features, folds, scores, bootstrap draws, code, and pinned data retrieval instructions. Independent checks use fresh public signals. The scope is clinical label ranking in 33 selected SEEG patients, with independent patients assumed for the interval.

Its contact number result motivated the location baseline. We did not use its numerical outputs. We formed the current features from the source covariance package.

We used its pinned metadata, retrieval code, and 70 band covariance files. We checked all copied hashes and recalculated power from fresh public signals. Its labels and covariance inputs support the new patient holdout test.

Its related interictal high gamma result supplied context for the scope of patient exclusion and refitted uncertainty. Different bands, contact sets, references, and models prevent a band-specific comparison. We did not use its code, feature arrays, or fitted values.
