1 · What the graph read from it

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.

2 · The registry

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: Nutrient resorption refers to the process of transferring nutrients from senescing organs to living organs within plants for reuse. It is a key strategy enabling plants to conserve nutrients essential for growth and development. However, how stand structure influences nutrient resorption in different organs across stand developmental stages remains unclear. Methods: In this study, we conducted field investigations in 39 plots (20 m × 20 m) within Chinese fir plantations spanning four developmental stages, measuring nitrogen and phosphorus resorption efficiencies (NRE and PRE) in fine roots, twigs, leaves. We additionally calculated crown ratios, dead twig biomass, and relative growth rates within each plot. Results: Our results showed that stand density and relative growth rate decreased, while crown ratios increased and dead twig biomass initially increased rapidly before gradually declining during stand development. With stand aging, nitrogen concentrations increased in all organs, whereas phosphorus concentrations varied in aboveground vs. underground organs. Leaf NRE (NRE Discussion: Our results suggest management strategies for Chinese fir plantations: phosphorus addition in mature stands versus nitrogen supplementation in other stages, coupled with either increased initial planting density in young forests or preemptive understory canopy pruning to optimize nutrient resorption - particularly in nutrient-limited environments.
