Sleep apnea (OSA) screening leaderboard

Stanford enriched cohort: Pearson r

1 reported result for sleep apnea (OSA) screening on Stanford enriched cohort, ranked by Pearson r. Every row cites its source publication.

Last updated

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 Pearson correlation (labs / continuous) (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.

Only one result has been reported on this dataset and metric so far, so this is a reference point rather than a multi-method comparison.

Evaluation protocol: Agreement between the estimated and the PSG/HSAT-scored apnea-hypopnea index (AHI).

Evaluation details · caveat

Site: wrist; SpO₂ used: not stated

Not ranked: eAHI vs OAHI 4%; the comparison is plotted in Alavi et al. Fig. 2c (scatter, both lab nights), but r = 0.87 is not printed on the figure or caption and the body text is paywalled, so the value is still sourced from the Khayat & Floyd commentary; First author Arash Alavi stated in an email to ChatPPG (2026-10-30) that r = 0.87 (225 night-level pairs, OAHI 4%) appears on p. 6 of Alavi et al. JCSM 2026 (Fig. 2c). Author-reported; the paywalled text wasn't independently checked.; Samsung-funded.

0.87

Rows are ranked only within this task × dataset × metric and one protocol group. Protocols can still differ in detail; read each method's evaluation details before comparing.
