Sequence characterization, molecular phylogeny reconstruction and recombination analysis of the large RNA of Tomato spotted wilt virus (Tospovirus: Bunyaviridae) from the United States.
Article in BMC research notes, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundTomato spotted wilt virus (TSWV; Tospovirus: Bunyaviridae) has been an economically important virus in the USA for over 30 years. However the complete sequence of only one TSWV isolate PA01 characterized from pepper in Pennsylvania is available.
resultsThe large (L) RNA of a TSWV WA-USA isolate was cloned and sequenced. It consisted of 8914 nucleotides (nt) encoding a single open reading frame of 8640 nts in the viral-complementary sense. The ORF potentially codes for RNA-dependent RNA polymerase (RdRp) of 330.9 kDa. Two untranslated regions of 241 and 33 nucleotides were present at the 5' and 3' termini, respectively that shared conserved tospoviral sequences. Phylogenetic analysis using nucleotide sequences of the complete L RNA showed that TSWV WA-USA isolate clustered with the American and Asian TSWV isolates which formed a distinct clade from Euro-Asiatic Tospoviruses. Phylogeny of the amino acid sequence of all tospoviral RdRps used in this study showed that all the known TSWV isolates including the USA isolate described in this study formed a distinct and a close cluster with that of Impateins necrotic spot virus. Multiple sequence alignment revealed conserved motifs in the RdRp of TSWV. Recombination analysis identified two recombinants including the TSWV WA-USA isolate. Among them, three recombination events were detected in the conserved motifs of the RdRp.
conclusionsSequence analysis and phylogenetic analysis of the L RNA showed distinct clustering with selected TSWV isolates reported from elsewhere. Conserved motifs in the core polymerase region of the RdRp and recombination events were identified.
