The 95% interval for extra five-minute PVT speed loss under assigned sleep restriction included zero in 85 ds000201 v1.0.3 adults after condition orders were balanced

We tested whether assigned partial sleep restriction increased speed loss during a five-minute psychomotor vigilance test (PVT). We used public response records from the Stockholm Sleepy Brain study. The primary estimate was 0.00419 inverse seconds (1/s). Its 95% person bootstrap interval was −0.08652 to 0.09543 1/s. The interval includes zero and leaves both directions possible. These results do not establish equal performance between the two sleep conditions. The new contribution is a time contrast for this public cohort. The package also supplies code that balances condition orders and preserves paired visits during resampling. It includes source bytes, source hashes, person scores, resampling indices, assignment draws, and independent checks. This contribution is a secondary analysis. It is not a new cohort or an independent replication of prior PVT results.
