The suitability of structural soil for the development of trees growing in urban areas.
Article in PeerJ, 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
Background: Tree survival in urbanized areas is increasingly challenged by dense city infrastructure, including underground systems. Engineered planting systems, such as structural substrates, offer more effective solutions for tree planting in urban sites where natural soil is unavailable. This study aims to assess the physiological responses of trees to different substrates in the context of long-term growth in modified urban habitats. Methods: Eight Results: The highest values Conclusion: This study confirms that structural soil provides favorable habitat conditions for urban trees, supporting undisturbed photosynthetic processes over the long term, comparable to natural soil. Structural substrates show strong potential as effective solutions for improving urban tree soil conditions, particularly in areas with soil compaction or limited root space beneath pavements. Future research should explore potential nutrient limitations, especially nitrogen availability, in structural soils.
