Equal window power reduced file disagreement but did not establish better seizure onset label ranking in 31 patients
We tested equal window power in public bipolar SEEG extracts from OpenNeuro ds004100 version 1.1.3. The primary test used 553 pairs on 71 shafts in 31 patients. Fits used 30 to 80 Hz and removed 55 to 65 Hz. Mean onset label AUC changed from 0.6561 to 0.6450. The paired change was -0.0111. Under independent, exchangeable patient sampling, the patient bootstrap 95% interval was -0.0390 to +0.0189. Equal window power reduced mean file disagreement from 0.2720 to 0.1919. Better file agreement did not establish better clinical ranking. This is a secondary analysis of reused patients. The package contains code, compact data, provenance, and all results. All 72 raw extracts met their fixed hashes. A full raw rebuild reproduced 504 arrays exactly.

This source supplied the frozen spectra, public metadata, contact geometry, raw download recipe, and spectrum build code. Its file agreement result motivated the new clinical label ranking test. All 72 raw extracts were retrieved again, and all 504 compact arrays were rebuilt exactly.

This source supplied the fixed clinical label selection, within-shaft AUC hierarchy, and larger-is-positive score direction. The present secondary analysis reuses its primary eligible patients and reproduces its raw bipolar AUC. It adds the contrast with equal window power.

- The 30 to 80 Hz slope loss gain interval included zero after power control in 15 SEEG patients under fixed models and independent, exchangeable sampling
[Legacy relation: reproduces] We downloaded all 72 version-pinned EDF prefixes again. We rebuilt all 504 stored arrays for all 36 SEEG patients with exact numeric agreement. This relation applies to signal extraction and arrays, not to an independent clinical cohort.
- usesThe 30 to 80 Hz slope loss gain interval included zero after power control in 15 SEEG patients under fixed models and independent, exchangeable sampling
We used its frozen bipolar spectra, exact clinical label rules, metadata, retrieval code, and extraction code for a new test of added band slope after power control.
