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 (Cunninghamia lanceolata) is a cornerstone timber species in China. It has been cultivated for millennia and introduced globally. Here, we present a high-quality chromosome-scale reference genome, revealing a recent burst of transposable elements during the Pliocene. While no whole-genome duplications are observed, tandem and proximal gene duplications expand families linked to environmental adaptation. Population resequencing of 87 provenance accessions and 15 ancient trees, including specimens planted in 1176 by the esteemed Neo-Confucianist Zhu Xi, reveals three principal phylogenetic groups corresponding to major geographic regions: the Yangtze River basin (group I), the Wuyi-Nanling region (group II; superior provenance), and regions along the Hakka migration route (group III). The Wuyi Mountains likely represent a historical hub of germplasm exchange and genetic connectivity. Analysis of 90 advanced-generation seed orchard progeny individuals and 13 elite clones reveals a marked bias in modern breeding practices toward specific lineages (primarily group II), whereas group I, which includes nearly all ancient trees, remains underutilized. These findings provide a genomic framework for understanding the domestication continuum, anthropogenic reshaping, and lineage-biased selection in C. lanceolata, offering insights for sustainable improvement and conservation.
