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
To study hybrid speciation in wheatgrass Douglasdeweya wangii and to investigate the evolutionary pattern of nuclear ribosomal DNA (nrDNA) internal transcribed spacer sequences (ITSs) in allotetraploids, DNA sequence variation of ITSs and chloroplast trnL-F sequences from D. wangii and its putative donors were analyzed. The ITSs revealed that D. wangii had an StP genome composition. Most accessions of D. wangii had one parental ITS copy in their genome, one accession had two parental ITSs. The trnL-F sequences revealed an especially close relationship of Pseudoroegneria to all D. wangii individuals included, and the two accessions of Pseudoroegneria tauri (PI401324 and PI401331) were maternal candidates of the studied D. wangii individuals. Both of ITS and trnL-F trees suggested multiple origins and recurrent hybridization of D. wangii. Thus, the results suggested that: (1) the St and P genome in allotetraploid D. wangii were donated by Pseudoroegneria and Agropyron, respectively;(2) Pseudoroegneria was the maternal donor of D. wangii, and P. tauri 26 (accession PI401324) and P. tauri 27 (accession PI401331) were most likely the potential candidates of maternal donors; (3) D. wangii individuals studied here showed multiple origins and experienced recurrent hybridization; and (4) bidirectional interlocus concerted evolution of ITSs had occurred in most D. wangii accessions, while in one accession concerted evolution among homeologous loci did not occur.
