Comparative chloroplast genome and phylogenetic analyses of Chinese Polyspora.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
Polyspora Sweet (Theaceae) are winter ornamental landscape plants native to southern and southeastern Asia, some of which have medicinal value. The chloroplast (cp) genome data of Polyspora are scarce, and the gene evolution and interspecific relationship are still unclear. In this study, we sequenced and annotated Polyspora chrysandra cp genome and combined it with previously published genomes for other Chinese Polyspora species. The results showed that cp genomes of six Chinese Polyspora varied in length between 156,452 bp (P. chrysandra) and 157,066 bp (P. speciosa), but all contained 132 genes, with GC content of 37.3%, and highly similar genes distribution and codon usage. A total of eleven intergenic spacer regions were found having the highest levels of divergence, and eight divergence hotspots were identified as molecular markers for Phylogeography and genetic diversity studies in Polyspora. Gene selection pressure suggested that five genes were subjected to positive selection. Phylogenetic relationships among Polyspora species based on the complete cp genomes were supported strongly, indicating that the cp genomes have the potential to be used as super barcodes for further analysis of the phylogeny of the entire genus. The cp genomes of Chinese Polyspora species will provide valuable information for species identification, molecular breeding and evolutionary analysis of genus Polyspora.
