13 reported results for sleep apnea (OSA) screening on Stanford enriched cohort, ranked by specificity. Every row cites its source publication.

Last updated Nov 2, 2026

These are research results as reported by each study, shown for education. A wearable or model result is not a diagnosis; talk to a clinician about a sleep study if you have concerns about sleep apnea.

This page ranks every result ChatPPG has recorded for sleep apnea (OSA) screening on Stanford enriched cohort, measured by Specificity at a stated threshold / operating point (higher is better). Each number is copied from the publication cited in its row, and ranks apply only within this dataset and metric and this protocol group.

Evaluation protocol: Moderate-to-severe OSA (AHI ≥ 15) classification against the reference sleep study.
