Utility of the Amborella trichopoda expansin superfamily in elucidating the history of angiosperm expansins.
Article in Journal of plant research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Expansins form a superfamily of plant proteins that assist in cell wall loosening during growth and development. The superfamily is divided into four families: EXPA, EXPB, EXLA, and EXLB (Sampedro and Cosgrove in Genome Biol 6:242, 2005. doi: 10.1186/gb-2005-6-12-242 ). Previous studies on Arabidopsis, rice, and Populus trichocarpa have clarified the evolutionary history of expansins in angiosperms (Sampedro et al. in Plant J 44:409-419, 2005. doi: 10.1111/j.1365-313X.2005.02540.x ). Amborella trichopoda is a flowering plant that diverged very early. Thus, it is a sister lineage to all other extant angiosperms (Amborella Genome Project in 342:1241089, 2013. doi: 10.1126/science.1241089 ). Because of this relationship, comparing the A. trichopoda expansin superfamily with those of other flowering plants may indicate which expansin genes were present in the last common ancestor of all angiosperms. The A. trichopoda expansin superfamily was assembled using BLAST searches with angiosperm expansin queries. The search results were analyzed and annotated to isolate the complete A. trichopoda expansin superfamily. This superfamily is similar to other angiosperm expansin superfamilies, but is somewhat smaller. This is likely because of a lack of genome duplication events (Amborella Genome Project 2013). Phylogenetic and syntenic analyses of A. trichopoda expansins have improved our understanding of the evolutionary history of expansins in angiosperms. Nearly all of the A. trichopoda expansins were placed into an existing Arabidopsis-rice expansin clade. Based on the results of phylogenetic and syntenic analyses, we estimate there were 12-13 EXPA genes, 2 EXPB genes, 1 EXLA gene, and 2 EXLB genes in the last common ancestor of all angiosperms.
