A reproducible remote sensing landscape metrics framework for assessing long term changes in urban green spaces.
Article in iScience, 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
Rapid urban expansion and land-use change have altered the extent and spatial configuration of urban green spaces, with important implications for ecological sustainability and urban quality of life. This study provides a framework for assessing spatiotemporal dynamics of urban green spaces by examining long-term changes in Shiraz, Iran, over 20 years, focusing on fragmentation and connectivity patterns. Using Landsat imagery and NDVI, vegetation changes were quantified and analyzed in ENVI, ArcMap, and R. Results indicate increased fragmentation, reduced connectivity, and dominance of small, isolated patches in central and southern parts of the city. Landscape metrics reveal a decline in spatial diversity and ecological coherence, suggesting reduced capacity for ecosystem service delivery. By integrating remote sensing, landscape metrics, and statistical analysis, this study offers an assessment of green space transformations applicable to other urban contexts. Findings emphasize the need for targeted planning to mitigate fragmentation and strengthen green space connectivity.
