Evaluation of the Barcelona Superblocks 'Green Corridor' project on the quality of public space from a health determinants perspective.
Article in European journal of public health, 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
Urban design has a direct impact on health and health inequalities. The Barcelona City Council implemented the Green Corridor project in 2022 in several streets of the Eixample district. The objective of the present study was to assess the effect of this project on the quality of public space from a health perspective approach. A quasi-experimental study was performed. The intervention group consisted of a sample of street sections of the intervened streets, and the comparison group consisted of a sample of street sections of a nearby street. The quality of public space was assessed in both groups before (2022) and after (2024) the intervention was implemented using an instrument designed ad hoc, which assessed eight different dimensions and several subdimensions. A difference-in-differences analysis was performed to compare pre-post differences between the intervention and comparison streets. In the intervention streets, significant improvements were observed in all the dimensions assessed. Greatest differences between the intervention and comparison groups were observed in the natural areas dimension (4.94 points difference), followed by the maintenance and cleanliness dimension (2.55 points), architectonic characteristics (2.28 points), safety (1.61 points), and environmental characteristics (1.00 points). Urban design transformations such as the Green Corridor project can improve living conditions in neighbourhoods by increasing urban green spaces and facilities, reducing motorized traffic, improving walkability, enhancing air and noise quality, and promoting social interaction, all of which can have a beneficial impact on residents' physical and mental health.
