Greenspace and intestinal diseases: a systematic review and meta-analysis.
Synthesis in BMC public health, 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
Greenspace has been reported potential therapeutically beneficial for intestinal diseases, yet the findings remain controversial Current researches demonstrate diversity in the assessment of greenspace and involve broad population groups, with the publication bias remaining a concern. This study offers convincing and reliable evidence supporting the beneficial effects of greenspace exposure on intestinal health, through a systematic review and meta-analysis examining the association between greenspace and intestinal disorders. The Greenspace exposure was primarily assessed using the Normalized Difference Vegetation Index (NDVI) and residential proximity to greenspaces. A comprehensive assessment was conducted concurrently by integrating various methods, such as land-use and satellite image data. This research encompassed a variety of intestinal conditions, such as inflammatory bowel disease (IBD), Crohn's disease (CD), ulcerative colitis (UC), colorectal cancer (CRC), and diarrhea. A search was performed cross four English and two Chinese databases, yielding nine studies for systematic review and eight for meta-analysis from 11,497 identified records. The results illustrated a significant protective effect of greenspaces against CD and IBD as well as a potentially protective effect against diarrhea. Nonetheless, no significant association was detected for UC or CRC. The study established that greenspaces could influence intestinal health through potential mechanisms such as improved air quality, enhanced microbial diversity, and reduced stress. These findings provide a solid basis for developing healthier urban environments and advancing strategies for prevention and treatment of intestinal diseases.Trial registration Registration number: CRD42024625968.
