Genome analysis of the novel putative rotavirus species K.
Article in Virus research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
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
Rotaviruses are causative agents of diarrhea in humans and animals. Currently, the species rotavirus A-J (RVA-RVJ) and the putative species RVK and RVL are defined, mainly based on their genome sequence identities. RVK strains were first identified in 2019 in common shrews (Sorex aranaeus) in Germany; however, only short sequence fragments were available so far. Here, we analyzed the complete coding regions of strain RVK/shrew-wt/GER/KS14-0241/2013, which showed highest sequence identities with RVC. The amino acid sequence identity of VP6, which is used for rotavirus species definition, reached only 51% with other rotavirus reference strains thus confirming classification of RVK as a separate species. Phylogenetic analyses for the deduced amino acid sequences of all 11 virus proteins showed, that for most of them RVK and RVC formed a common branch within the RVA-like phylogenetic clade. Only the tree for the highly variable NSP4 showed a different branching; however, with very low bootstrap support. Comparison of partial nucleotide sequences of other RVK strains from common shrews of different regions in Germany indicated a high degree of sequence variability (61-97% identity) within the putative species. These RVK strains clustered separately from RVC genotype reference strains in phylogenetic trees indicating diversification of RVK independent from RVC. The results indicate that RVK represents a novel rotavirus species, which is most closely related to RVC.
