First complete genome sequence of an isolate of cowpea severe mosaic virus from South America.

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
In this study, the complete nucleotide sequence of a Brazilian isolate of cowpea severe mosaic virus (CPSMV) is presented for the first time. To date, the CPSMV-DG isolate, from the USA, is the only one with the complete known genome. High-throughput sequencing (Illumina HiSeq) and Sanger sequencing of the total RNA extract from a cowpea plant collected in Teresina city, Brazil, revealed the genome sequence of the CPSMV-Ter1 isolate. RNA-1 and RNA-2 are, respectively, 5921 and 3465 nucleotides (nt) long without the poly(A) tail, and show 77.91% and 76.08% nt sequence identity with CPSMV-DG, considered the type isolate of the species. The open reading frames (ORFs) were determined and the cleavage sites of the polyproteins were predicted. Although the two isolates show a similar genomic organization, there was a low percentage of sequence identity between Ter1 and DG. Furthermore, pairwise comparisons of a partial RNA-1 fragment between CPSMV-Ter1 and 11 CPSMV isolates from Brazil indicated 94.6 to 94.8% nt and 98.9% to 99.4% aa sequence identities.
