Fitbit Physical Activity and Sleep Data in the All of Us Research Program: Data Exploration and Processing Considerations for Research.
Article in Medicine and science in sports and exercise, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe All of Us Research Program is a national effort to enroll ≥1 million participants for health research. The program enables participants to donate Fitbit data, providing a unique dataset for physical activity (PA) and sleep research. This study characterizes Fitbit device data in the All of Us cohort version 8 (v8) data release to facilitate use by researchers.
methodsData were inspected and quality control guardrails were implemented. Days 15 to 21 (inclusive) postconsent date were selected for analysis of demographic characteristics, wear days, and wear time proxy variables.
resultsOn days 15 to 21 postconsent, the v8 All of Us Fitbit cohort consisted of n = 30,445 participants with PA and/or sleep summary data from 160,487 person-days. Almost all participants (99%) provided both PA and sleep data. The sample consisted of 57% bring-your-own-device participants and 43% Wearables Enhancing All of Us Research (WEAR) participants provided with a device. The majority of participants were non-Hispanic White (66%) and female (68%). Seventy percent of the sample had ≥5 d of summary data available. Using heart rate data as a proxy for wear, participants averaged 1310 ± 170 min·d -1 of wear time on wear days, or roughly 21 h and 50 min. The Fitbit Charge series were the most common devices worn in the cohort.
conclusionsConsiderations for working with All of Us Fitbit data (v8) are discussed and include rolling dates of primary consent, date shift implementation, proprietary Fitbit algorithm, valid day methodology, missing data assumptions, photoplethysmography technology, device version data, and population representation.
