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

Paulownia species are important ecological, economic and ornamental species, but their phylogenetic relationship remains unclear, which seriously affects the development and utilization of these important resources. The complete chloroplast genomes of six Paulownia species were assembled by next-generation sequencing data. By adding two known Paulownia chloroplast genomes to these six assembled genomes, we performed the comparative analysis and phylogenetic tree reconstruction of Paulownia. The results indicated that the chloroplast genomes of Paulownia species ranged in size from 154,107 to 154,694 bp. These chloroplast genomes contained 117 unique functional genes, including 80 protein-coding genes, four rRNA genes, and 33 tRNA genes. Twelve hotspot regions, five protein-coding genes and seven noncoding regions, were identified in the chloroplast genomes that showed high levels of sequence variation. Additionally, positive selection was observed in three genes, rps2, rbcL and ndhG. The maximum likelihood (ML) and Bayesian (BI) analysis strongly supported the monophyletic origin of Paulownia species, which clustered into two major clades: One clade included P. coreana, P. tomentosa and P. kawakamii, while the other clade comprised the 5 other species including P. fargesii and P. australis. This study provides useful genetic information for phylogenetic reconstruction, taxonomic discrepancies, and studying species evolution and phylogeography in Paulownia.
