Spatiotemporal changes in inter-city sustainability impacts linked to emission challenges worldwide.
Article in Nature communications, 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
Atmospheric emissions pose significant challenges to achieving the Sustainable Development Goals (SDGs). As key sources of emissions, cities are also critical actors in driving sustainable transitions. Their performance on emission-related SDG indicators is shaped not only by local factors but also by inter-city interactions. However, the spatial and temporal heterogeneity of these interactions remain poorly understood. Here, we investigate inter-city SDG interactions across 4,116 cities worldwide from 2010 to 2020, and simulate SDG performance under five interaction scenarios, including isolated and collaborative conditions. Results reveal that a 10% improvement in SDG 11.6 (particulate matter), SDG 12.4 (gaseous pollutants), and SDG 13.2 (greenhouse gases) in other cities can boost the focal city's performance by 0.450%, 0.390%, and 0.200%, respectively. Most cities (93.51%) are influenced by other cities. Inter-city coordination can improve SDG performance by 10.81% compared to isolated efforts. These findings highlight the importance of coordinated strategies to enhance urban sustainability.
