Identification and characterization of a novel carlavirus isolated from viburnum (Viburnum opulus) in Aotearoa New Zealand.

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
The genus Viburnum includes more than 150 species of ornamental shrubs and trees that are cultivated worldwide. In Aotearoa New Zealand (NZ), V. opulus is the most popular of the species widely used in landscaping. To date, alfalfa mosaic virus (AMV) has been the only virus reported in viburnum in NZ. Here, we report the identification and molecular characterization of a novel carlavirus, tentatively named "viburnum carlavirus 1" (VibCV1), from a V. opulus plant coinfected with AMV. The virus was characterized using high-throughput sequencing, transmission electron microscopy, and herbaceous indexing. The complete genome of VibCV1 is 8,444 nucleotides in length and contains six open reading frames, with an organization typical of members of the genus Carlavirus. Phylogenetic analysis revealed that VibCV1 is most closely related to helleborus mosaic virus (HeMV), sharing 80.24% and 85.48% amino acid sequence identity in the replicase and coat protein, respectively. These values lie on the borderline of the current species demarcation criteria for the family Betaflexiviridae. Considering its distinct natural host range, limited distribution, and phylogenetic divergence from HeMV, we suggest that VibCV1 possibly represents a new species within the genus Carlavirus. The low incidence of VibCV1 in NZ viburnum populations is also discussed.
