Under exchangeable outcome labels within therapy, a test did not detect a mean group difference in gamma treatment ranks from two 60-second SEEG records in 36 patients
We tested a fixed gamma power rank score in 36 patients from OpenNeuro ds004100, version 1.1.3. Each patient had two 60-second SEEG records. The score ranked treated contacts against untreated contacts. We compared source outcome S with F within ablation and resection groups. The mean S minus F contrast, weighted by therapy group size, was -0.0293. The 95 percent patient bootstrap interval was -0.1479 to +0.0917. A label test within therapy gave p = 0.66236, under outcome exchangeability. The test did not detect a mean group difference. The interval permits effects in either direction. The score choice came from earlier onset-label work in this cohort. This is a secondary outcome study, not independent score validation. The package preserves all 36 spectra, clinical labels, patient scores, code, test draws, source versions, raw examples, checks, and reproduction instructions.

This work supplied the original two-record SEEG spectra, contact quality rules, EDF retrieval code, and Welch method through the direct input archive. We preserved its code and source records. We checked two raw records with a separate decoder and SciPy spectrum calculation.

We used its archived absolute gamma features, all 36 patient spectra, source clinical metadata, and preserved retrieval records. We added a fixed patient outcome test within therapy groups. The new package preserves these inputs and checks their hashes.
