Correlates of Fitness Tracker Ownership and Use in Cancer Survivors: Cross-Sectional Survey.
Article in JMIR cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundConsumer fitness tracker devices offer scalable opportunities to monitor real-world behavior and support health in cancer survivorship. However, adoption and sustained use outside structured research settings remain incompletely characterized, limiting their integration into survivorship care.
objectiveThe primary objectives were to describe the prevalence of fitness tracker ownership and use patterns among cancer survivors and to identify sociodemographic, psychosocial, and usability-related correlates of device ownership and frequent use.
methodsWe conducted a cross-sectional survey of 893 cancer survivors enrolled in the Total Cancer Care protocol at a comprehensive cancer center. Participants completed an adapted online questionnaire assessing fitness tracker ownership, frequency of use, and perceived barriers and facilitators. Multivariable logistic regression models were used to identify sociodemographic, psychosocial, and usability-related correlates of device ownership and frequent use.
resultsMore than half of the participants (506/893, 56.7%) reported owning a fitness tracker, and among owners, 82.2% (416/506) reported frequent use (most days or every day), including 71.3% (361/506) who wore the device every day. The most commonly used devices were the Apple iWatch (272/506, 53.8%) and Fitbit (147/506, 29.1%). In multivariable analyses, fitness tracker ownership was independently associated with sex, household income, and cancer site. Male participants had lower odds of ownership (adjusted odds ratio [aOR] 0.61, 95% CI 0.42-0.87; P=.006), while higher household income was associated with greater ownership (US $50,000-$99,999: aOR 1.70, 95% CI 1.13-2.57; P=.01; ≥US $100,000: aOR 3.64, 95% CI 2.41-5.50; P<.001). Ownership also differed by cancer site. Among owners, frequent use was concurrently and inversely associated with self-reported device discomfort (P<.001), low motivation (P<.001), information overload (P=.04), and limited app integration (P=.007).
conclusionsIn this single-center, predominantly White, higher-income sample of cancer survivors, fitness tracker ownership was common and patterned by demographic and socioeconomic characteristics, while sustained engagement among device owners was associated with psychosocial and usability factors. These findings suggest that scalable, fitness tracker-enabled survivorship care will need to address both structural disparities in ownership as well as behavioral readiness and user experience to ensure clinically meaningful implementation.
