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

Here, we describe a novel ourmia-like virus, Botryosphaeria dothidea ourmia-like virus 3 (BdOLV3), obtained from the phytopathogenic fungus Botryosphaeria dothidea strain ZM211299-2 infecting apple shoots in Shandong province of China. The genome of BdOLV3 is a positive-sense single-stranded RNA with a length of 2,650 nucleotides (nt), containing a large open reading frame (ORF) that encodes a putative RNA-dependent RNA polymerase (RdRp) consisting of 673 amino acids (aa) with a molecular mass of 75.53 kDa. This RdRp protein contains eight typical conserved motifs associated with ourmia-like viruses. BLASTp analysis revealed that the RdRp protein of BdOLV3 had the highest similarity (61.98%, 61.83%, and 51.47% identity, respectively) to viruses previously identified as Plasmopara viticola lesion associated ourmia-like virus 45, Erysiphe necator associated ourmia-like virus 130, and Magnaporthe oryzae botourmiavirus 7. Phylogenetic analysis based on RdRp sequences indicated that BdOLV3 is a new member of the genus Epsilonscleroulivirus in the family Botourmiaviridae. This is the first report of the complete genomic sequence of a member of the genus Epsilonscleroulivirus found in B. dothidea.
