Identification of a putative novel carlavirus infecting Gynura bicolor in China.
Article in Archives of virology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In July 2023, 25 leaf samples of Gynura bicolor showing mosaic and chlorosis symptoms were collected in Hohhot, Inner Mongolia, China. Total RNA was extracted from pooled, homogenized tissues was subjected to high-throughput sequencing (HTS), which revealed the presence of four known viruses and an unknown virus. The complete genome sequence of the unknown virus was obtained using RT-PCR and RACE, yielding an 8,750-nt positive-sense single-stranded RNA genome with six open reading frames. Sequence analysis revealed that its replicase gene shared 71.6% nucleotide and 78.4% amino acid sequence identity with pseudostellaria heterophylla carlavirus 1 (PhCV1). These values are below the species demarcation threshold. Phylogenetic analysis grouped the virus with members of the genus Carlavirus, supporting its classification as a novel member of this genus. We have tentatively designeatd it "gynura bicolor carlavirus" (GbCV). This is the first report of a carlavirus infecting G. bicolor.
