Construction of a core collection of Notopterygii Rhizoma et Radix based on molecular phylogeography.

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
backgroundAs endangered medicinal species (Category III protected plants in China) and as authentic traditional Chinese medicines, Notopterygium incisum Ting ex H. T. Chang and N. franchetii Boiss. require urgent conservation of their germplasm resources. While core collections offer an efficient solution for preserving genetic diversity, no such resource currently exists for these species despite their ecological and pharmacological importance.
methodsIn this study, three chloroplast DNA regions (rbcL, matK, and trnS-trnG) and the nuclear ribosomal ITS sequence were employed as molecular markers to conduct phylogeographic analyses of N. incisum and N. franchetii, and their core collections were constructed through stratified sampling of evolutionary significant haplotypes.
resultsNetwork analyses revealed complete cpDNA differentiation between species (12 vs. 10 haplotypes separated by ≥ 5 mutations), while ITS data showed limited historical introgression. Wild populations exhibited strong genetic structure (G
conclusionUsing integrated cpDNA and ITS markers, we established optimized core collections for both species (N. incisum: 50-103 accessions; N. franchetii: 30-40 accessions) that effectively preserved genetic diversity. The dual-marker approach resolved cultivated populations' paradoxical genetic patterns (higher diversity but lower differentiation) and provides a conservation model for medicinal plants facing anthropogenic pressures.
