Exploring the role of place visitation big data on small area health measure estimation.
Article in Computational urban science, 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
Population-level health measures at small geographic scales (e.g., census tracts), including health conditions, preventive behaviors, risk factors, and overall health status, are crucial for guiding effective health planning and policymaking. It has been well established that demographic and social determinants of health (SDOH) factors contribute to health disparities and thus are usually applied to predict health measure estimation. However, demographic and SDOH indicators are often static and fail to account for the dynamic aspects of daily life. This study explores the role of resident routine activity derived from place visitation big data in estimating health measures at the census tract level in the United States and tests this hypothesis across both urban and rural regions. Hierarchical regression analysis was conducted using demographic and SDOH data (12 variables from the 2019 American Community Survey), and smartphone-based place visitation data (visitation rates to 120 categories of places from SafeGraph Patterns). We analyzed 22 health measures from the CDC's Population-Level Analysis and Community Estimates (PLACES) dataset, classifying census tracts as urban or rural using the USDA's Rural-Urban Commuting Area (RUCA) codes. The results showed that incorporating place visitation data significantly contributes to health measure estimation beyond traditional demographic and SDOH variables (mean R² increased by 7.5%). This improvement varied substantially between urban (7.6%) and rural areas (12.5%).
