1 · What the graph read from it

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.

2 · The registry

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

Bacterial wilt caused by Ralstonia solanacearum species complex (RSSC) is a significant threat to agriculture due to the pathogen's broad host range and persistence in soil. Bacteriophages (phages) are being explored as biocontrol agents, and such strategies are gaining interest. In this study, we isolated and characterized vB_RsoP_HXg1W, a novel phage propagated on R. pseudosolanacearum GMI1000. The phage has a linear double-stranded DNA genome of 40,184 bp with a GC content of 62.3%, and displays an icosahedral head with a short tail. A total of 51 open reading frames (ORFs) were identified, and no tRNA genes were detected. Comparative genomic and phylogenetic analyses revealed that vB_RsoP_HXg1W is closely related to Ralstonia phage p2137, p2106, and RpY2, and clusters within the genus Serkorvirus in the family Autotranscriptaviridae. VIRIDIC analysis revealed a maximum intergenomic similarity of 84.7% to the closest included relative, supporting vB_RsoP_HXg1W as a putative novel species-level member of Serkorvirus. These findings contribute to the understanding of RSSC-infecting phages and provide a foundation for further exploration of phage evolution, host range, and biocontrol relevant traits.
