Conservative allocation strategy of nitrogen and phosphorus among leaves, stems and roots of Artemisia species.

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
backgroundUnderstanding the allocation of nitrogen (N) and phosphorous (P) among various plant organs is crucial for gaining insights into plant nutrient uptake, utilization strategies, and overall growth and life history strategies. However, little is known about the nitrogen and phosphorus allocation strategies among the three major plant organs (e.g., leaves, stems, and roots), particularly in phylogenetically closely related species. To investigate N and P allocation strategies among different plant organs, we collected 912 individuals of 62 Artemisia species, encompassing three subgenera, from 81 sites across a broad environmental expanse in China.
resultsAverage N and P concentration and N: P ratios in major plant organs of Artemisia species have significant variations among the subgenera and ecosystems. Across all 62 species, the numerical values of the scaling exponents of N(α
conclusionOur results found that the allocation of N and P among plant organs in Artemisia species differs at the subgenera level, suggesting that it is necessary to consider different subgenus levels when exploring plant nutrient concentration and allocation. Conversely, a conservative nutrient allocation strategy prevails at the ecosystem level. Thus, a key insight from these results is that nutrient allocation strategies of closely related species are phylogenetically conserved and are comparatively insensitive to local environmental conditions.
