Phylogenetic relationships and the identification of allopolyploidy in circumpolar Silene sect. Physolychnis.
Article in American journal of botany, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
premiseSpecies complexes are groups of closely related species with ambiguous delimitation, often composed of recently diverged lineages. Polyploidization and uniparental reproduction (i.e., selfing and apomixis) can play important roles in the origin of species complexes. These complexes pose challenges for species-based scientific questions, such as the estimation of species richness or conservation prioritization.
methodsWe determined the potential of resolving taxonomically complex groups using target enrichment in the circumpolar Silene uralensis complex (Caryophyllaceae). We proposed a metric using genetic distances between phased alleles to distinguish diploids from allopolyploids.
resultsOur results identified geographic structure of populations, with the northern American and Greenlandic samples having a common ancestor. We found little phylogenetic support for the most recent taxonomic treatment of the Silene uralensis complex.
conclusionsThe study highlights the use of target enrichment in testing taxonomic hypotheses in diploids and the challenges of studying recently diverged lineages.
