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

Catalpa huangxin, a distinctive taxon within the genus Catalpa in China, is valued for its ornamental beauty and durable yellow heartwood. However, its wild populations are declining due to climate change and human activities, posing urgent conservation challenges. The unclear genetic diversity and population structure further complicate its protection and breeding efforts. To address these issues, this study employed RAD-seq to analyze 198 samples, including 169 C. huangxin, 24 Catalpa duclouxii, and 5 Catalpa ovata (outgroup), focusing on phylogeny, genetic diversity, gene flow, and dispersal routes. The results show that C. huangxin and C. duclouxii are distinct but closely related taxa. C. huangxin was divided into five subgroups with moderate genetic diversity (He = 0.2935, Ho = 0.4401). Subgroup 5 exhibited the highest diversity, but significant genetic differentiation (F
