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
backgroundPlant economic profiles involve trade-offs between many functional traits of a plant that are often used as indicators to characterize major adaptive strategies, thus providing insights into plant distribution, ecosystem processes, and function. However, research on plant economic profiles in extreme habitats is limited, and most studies on economic profiles have focused on single organs, with fewer studies on economic profiles among aboveground (leaf and stem) organs.
methodsTaking the desert area of Qaidam Basin as the research object, 8 leaf traits and 8 stem traits of 25 dominant woody plants accounting for more than 80% of biomass in 130 sample plots under different aridity gradients were quantitatively analyzed. The functional strategies and economic profiles of aboveground organs of desert plants adapted to arid environment were studied.
resultsTraits of leaves and stems represent distinct resource strategies. Leaf traits emphasize resource acquisition, while stem traits highlight conservation. The leaf economic spectrum (LES) and stem economic spectrum (SES) strategies showed an inverse pattern, with leaf traits shifting from opportunistic to conservative strategies and stem traits shifting from conservative to stabilizing strategies as aridity intensified, revealing an integrated aboveground economic spectrum of the plant along the aridity gradient. Moreover, there was a significant negative correlation between leaf and stem function strategies and reflected significant leaf-stem trade-offs.
conclusionThe functional traits of plants can reflect plant responses to environmental changes, and the aboveground economics spectrum helps researchers understand the response of plants as a whole to environmental differences, thus deepening the knowledge of the economic spectrum of plants. The patterns of economic profiles embodied by plants in response to aridity were revealed in this study. The trade-off between the LES and SES demonstrated the existence of an aboveground economic spectrum, providing a scientific basis for understanding the survival mode and adaptive variation pattern of desert plants.
