1 · What the graph read from it

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.

2 · The registry

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

The complete genomic sequence of a previously uncharacterized virus provisionally named "Bursera graveolens associated totivirus 1" (BgTV-1) was obtained from Bursera graveolens (Kunth) Triana & Planch., a tree known as "palo santo" in Ecuador. The BgTV-1 genome is a monopartite double-stranded RNA (dsRNA) that is 4794 nucleotides (nt) long (GenBank accession number ON988291). Phylogenetic analysis of the capsid protein (CP) and RNA-dependent RNA polymerase (RdRp) placed BgTV-1 in a clade with other plant-associated totiviruses. Amino acid (aa) sequence comparisons of putative BgTV-1 proteins showed the highest sequence similarity to those of taro-associated totivirus L (QFS21890.1-QFS21891.1) and Panax notoginseng virus A (YP_009225664.1- YP_009225665.1), with 51.4% and 49.8% identity, respectively, in the CP and 56.4% and 55.2% identity, respectively, in the RdRp. BgTV-1 was not detected in total RNA from either of the two endophytic fungi cultured from BgTV-1-positive B. graveolens leaves, suggesting that BgTV-1 may be a plant-infecting totivirus. Based on its distinct host and the low aa sequence similarity between the CP of BgTV-1 and its counterparts from the closest relatives, the virus described in this study should be assigned as a new member of the genus Totivirus.
