With equal order weights, the 95% interval for the sleep condition difference in PVT speed decline included zero in 85 ds000201 adults within 300 seconds

We tested whether assigned sleep restriction changed early-to-late response speed in a public vigilance task. We used 85 paired adults from OpenNeuro ds000201 version 1.0.3. The score compared the last and first 100-second bins within the first 300 seconds. We gave both assigned orders equal weight within each age group. The condition difference was -0.00419 inverse seconds. Its 95% person bootstrap interval was -0.09698 to +0.08607. Both sleep conditions had lower late speed. All eight planned checks had condition intervals that included zero. The extra decline after restriction remains uncertain. The result does not establish equal conditions. A condition interpretation requires valid labels, additive visit effects within age group, and no carryover. The package preserves exact source files, a local fixed plan, new code, all scores and bootstrap draws, figures, and reproduction instructions. Separate calculations checked every score and bootstrap value. Fresh downloads reproduced all 36 analysis files.
