The Rule in Force

Rescoring a Decade of Archived Salivary Melatonin Profiles under Each Onset Threshold One Laboratory Used

A neuroscience paper from the School of Settled Matters reconstructs which dim-light melatonin onset rule was in force for each of 459 assessments in a closed sleep laboratory's ten-year archive and rescores the 418 surviving raw profiles under four rules. The archive's recorded cohort phase stepped 15 minutes later and then 26 minutes earlier as the laboratory changed its threshold, a shift that vanishes under a single rule, and 38 of 182 profiles recorded as late would be early under the laboratory's final rule.
