Phylogeography of herbarium specimens of asexually propagated paper mulberry [Broussonetia papyrifera (L.) L'Hér. ex Vent. (Moraceae)] reveals genetic diversity across the Pacific.
Article in Annals of botany, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Background and Aims: Paper mulberry or Broussonetia papyrifera (L.) L'Hér. ex Vent. (Moraceae) is a dioecious species native to continental South-east Asia and East Asia, including Taiwan, that was introduced to the Pacific by pre-historic voyagers and transported intentionally and propagated asexually across the full range of Austronesian expansion from Taiwan to East Polynesia. The aim of this study was to gain insight into the dispersal of paper mulberry into Oceania through the genetic analysis of herbaria samples which represent a more complete coverage of the historical geographical range of the species in the Pacific before later introductions and local extinctions occurred. Methods: DNA from 47 herbarium specimens of B. papyrifera collected from 1882 to 2006 from different islands of the Pacific was obtained under ancient DNA protocols. Genetic characterization was based on the ribosomal internal transcribed spacer ITS-1 sequence, a sex marker, the chloroplast ndhF-rpl32 intergenic spacer and a set of ten microsatellites developed for B. papyrifera. Key Results: Microsatellites allowed detection of 15 genotypes in Near and Remote Oceanian samples, in spite of the vegetative propagation of B. papyrifera in the Pacific. These genotypes are structured in two groups separating West and East Polynesia, and place Pitcairn in a pivotal position. We also detected the presence of male plants that carry the Polynesian chloroplast DNA (cpDNA) haplotype, in contrast to findings in contemporary B. papyrifera populations where only female plants bear the Polynesian cpDNA haplotype. Conclusions: For the first time, genetic diversity was detected among paper mulberry accessions from Remote Oceania. A clear separation between West and East Polynesia was found that may be indicative of pulses during its dispersal history. The pattern linking the genotypes within Remote Oceania reflects the importance of central Polynesia as a dispersal hub, in agreement with archaeological evidence.
