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

Chinese fir plantations are a major component of China's forest carbon sink, and their mitigation value depends not only on total biomass but also on how carbon is allocated among stems, crowns, and roots at the tree level. Carbon allocation responds to competition and resource availability, proxied by stand structure (initial planting density and dominance classes) and environmental conditions (site index and climate). Yet how planting density, site index, and climate are associated with allocation variation across dominance classes remains poorly quantified, limiting density- and site-adaptive management for carbon sequestration. We used long-term density experiments at three subtropical sites (Sichuan, Guangxi, and Fujian), comprising 45 plots and five initial planting densities (1,667 to 10,000 trees ha
