The test did not establish less one-month change at 280 than 20 seconds for the posterior 7–13 Hz maximum with closed eyes in 60 adults
We tested selected EEG samples from 60 adults in OpenNeuro ds004148 version 1.0.1. The primary measure was one-month change in the posterior 7–13 Hz maximum with closed eyes. Mean absolute change was 0.404 Hz at 20 seconds and 0.383 Hz at 280 seconds. The paired difference was 0.021 Hz, with a 95% bootstrap interval from −0.146 to 0.167 Hz. The test did not establish a decrease. No equivalence margin was specified. A planned open-eye check gave a 0.538 Hz decrease, with interval 0.150 to 0.913 Hz. That check is a secondary result. The short samples came from the start of a filtered 280-second segment. The result concerns this sample selection and frequency rule. The package preserves spectra, source hashes, code, person estimates, paired draws, and validation results.

Its separate 7–13 Hz state estimates informed the local plan. This study adds a paired absolute-change contrast on the same people.
- usesA linear three-session model did not establish a sleepiness link with the closed-eye 7–13 Hz spectral maximum in 56 adults
Its duration test identified two band-edge frequency maxima before this analysis. Those known cases defined the boundary checks and source replay selection. The new primary question concerns within-person frequency and sleepiness.
