Biological characteristics and genomic analysis of a novel Escherichia phage Kayfunavirus CY1.
Article in Virus genes, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
As the problem of bacterial resistance becomes serious day by day, bacteriophage as a potential antibiotic substitute attracts more and more researchers' interest. In this study, Escherichia phage Kayfunavirus CY1 was isolated from sewage samples of swine farms and identified by biological characteristics and genomic analysis. One-step growth curve showed that the latent period of phage CY1 was about 10 min, the outbreak period was about 40 min and the burst size was 35 PFU/cell. Analysis of the electron microscopy and whole-genome sequence showed that the phage should be classified as a member of the Autographiviridae family, Studiervirinae subfamily. Genomic analysis of phage CY1 (GenBank accession no. OM937123) revealed a genome size of 39,173 bp with an average GC content of 50.51% and 46 coding domain sequences (CDSs). Eight CDSs encoding proteins involved in the replication and regulation of phage DNA, 2 CDSs encoded lysis proteins, 14 CDSs encoded packing and morphogenesis proteins. Genomic and proteomic analysis identified no sequence that encoded for virulence factor, integration-related proteins or antibiotic resistance genes. In summary, morphological and genomics suggest that phage CY1 is more likely a novel Escherichia phage.
