Measuring global human accessibility to essential daily necessities and services.
Article in Nature communications, 2025. 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
Equitable access to daily necessities and services is crucial for enhancing human quality of life and achieving the United Nations' Sustainable Development Goals. However, knowledge about global access to these essential resources remains limited and fragmented, due to the absence of a comprehensive infrastructure inventory and scalable accessibility measures. Here we compile a global database of points of interest to represent six essential infrastructure categories-living, healthcare, education, entertainment, public transit, and working. We use refined 30-meter resolution friction surface data to map travel time to these critical infrastructures as a proxy for accessibility across the urban-rural continuum and assess disparities across geographic, urbanization, and socio-economic contexts. Our results reveal uneven access in infrastructure availability, per capita distribution, and travel time. Globally, 62.8% (3.08 billion) and 82.5 % (4.04 billion) of urban residents live within a 15- and 30-minute walk of essential resources, respectively. These results highlight the need to optimize strategies for planning, allocation, and management of critical infrastructure to promote inclusive and sustainable development.
