Spatial distribution characteristics and influencing factors of China's important agricultural heritage systems.
Article in Scientific reports, 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
Agricultural heritage systems, a paradigm of harmonious symbiosis between humans and the natural environment, contain rich biodiversity and embody distinctive cultural values and historical significance. Macro-level spatial analysis is essential to understand agricultural heritage systems. This study is based on 188 China's Important Agricultural Heritage Systems (CIAHS) (2013-2023), utilizing spatial analysis methods such as the nearest neighbor index, standard deviational ellipse, kernel density analysis, and Geodetector to examine the spatial distribution characteristics and influencing factors of CIAHS. The results show an uneven distribution of CIAHS, characterized by significant regional discrepancies and an overall clustered spatial pattern. This pattern can be attributed to the combined effects of natural environmental factors (e.g., temperature, precipitation, topography, and water resources) and human environmental factors (e.g., economy, population, transportation, government response, and residents' attention), which interact synergistically. Among these factors, government response, temperature, and residents' attention play relatively greater roles in shaping the overall pattern. The study of the spatial distribution characteristics and influencing factors of CIAHS will enhance the understanding of the geographical evolution and regional variations of these resources, thus providing a scientific basis for their preservation and sustainable development.
