Diversity patterns of medicinal plants along elevational gradients across forest layers in Meihua Mountains, Fujian.
Article in Frontiers in plant science, 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
Introduction: Elucidating the diversity patterns and elevational distribution of medicinal plants is essential for biodiversity conservation and sustainable utilization in montane ecosystems. However, the variation in diversity across forest vertical layers and its responses to environmental gradients in mid-subtropical regions remain poorly understood. Methods: We surveyed medicinal plants in 93 plots across five elevational gradients (450-1800 m) in Meihua Mountain National Nature Reserve, China. Species composition and community structure in the tree, shrub, and herb layers were analyzed using importance values, Results: A total of 503 medicinal plant species (267 genera, 98 families) were recorded. Species richness followed the order shrub > herb > tree layer. Community composition showed clear elevational replacement. Discussion: This study demonstrate that medicinal plant diversity in mid-subtropical mountains is jointly shaped by vertical stratification and environmental filtering. The higher sensitivity of shrub and herb layers highlights their key role in maintaining biodiversity, whereas tree-layer stability reflects greater resistance to environmental variation. Canopy structure regulates understory diversity, with additional layer-specific effects from topographic and spatial factors. These results provide new insights into diversity maintenance mechanisms and offer guidance for conservation and forest management of medicinal plant resources.
