Molecular characterization of a novel umbra-like virus from Thuja orientalis (arborvitae) in South Korea.

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
A novel umbra-like virus was identified in arborvitae in South Korea using RNA sequencing (RNA-seq). The virus identified was tentatively named "arborvitae umbra-like virus" (AULV) and contained a 4,300-nucleotide genome organized into four non-structural open reading frames (ORFs). Cloning and Sanger sequencing were used to confirm the viral contig sequence and determine the size of the genome. Genome analysis indicated that ORF2 encodes an RNA-dependent RNA polymerase that is probably expressed through ribosomal frameshifting. ORF3 encodes a putative long-distance movement protein, while the functions of ORFs 1 and 4 are unknown. The virus lacks a coat protein gene. The genome of AULV shares 27.3%-48.4% nucleotide sequence identity with closely related umbraviruses. Phylogenetic analysis based on the complete genome sequences and amino acid sequences of the RNA-dependent RNA polymerase revealed that AULV forms a monophyletic lineage with Guiyang paspalum paspaloides tombus-like virus (GPpTV1). We suggest that AULV is a novel umbra-like virus belonging to the family Tombusviridae.
