Under patient independence, the 6 dB ratio score had higher SOZ label AUC after onset than 60 seconds earlier in 26 SEEG patients

This secondary study used public SEEG data from OpenNeuro ds004100 version 1.1.3. The fixed score used a 6 dB power ratio rise for two consecutive seconds. It ranked clinical seizure onset zone labels within the same named electrode shaft. The study used two seizures from each of 26 patients. Mean AUC was 0.710 after marked onset and 0.472 in a matched window 60 seconds earlier. The paired difference was 0.238, with a patient bootstrap 95 percent interval of 0.149 to 0.329. This interval assumes independent patients. The result concerns label ranking in this selected cohort. The package preserves source code, new control features, source pins, results, and reproduction instructions.

    [Legacy relation: reproduces] The rebuilt seizure powers matched its saved powers exactly. Its ratio score mean AUC of 0.7103 was reproduced in the same cohort. This is a numerical check, not an independent replication.

    The study used its 26-patient cohort, source pins, pair labels, and band-power code. It added a matched control window 60 seconds before onset.
