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

Environmental Vibrio cholerae strains isolated from a coastal brackish pond (Oyster Pond, Woods Hole, MA) carried a novel filamentous phage, VCY, which can exist as a host genome integrative form (IF) and a plasmid-like replicative form (RF). Outside the cell, the phage displays a morphology typical of Inovirus, with filamentous particles ∼1.8 μm in length and 7 nm in width. Four independent RF isolates had identical genomes, except for 8 single nucleotide polymorphisms clustered in two regions. The overall genome size is 7,103 bp with 11 putative open reading frames organized into three functional modules (replication, structure and assembly, and regulation). VCY shares sequence similarity with other filamentous phages (including cholera disease-associated CTX) in a highly mosaic manner, indicating evolution by horizontal gene transfer and recombination. VCY integrates in the vicinity of the putative translation initiation factor Sui1 in chromosome II of V. cholerae. A screen of 531 closely related host isolates showed that ∼40% harbored phages, with 27% and 13% carrying the IF and RF, respectively. The relative frequencies of the RF and IF differed among strains isolated from the pond or lagoon of Oyster Pond, suggesting that the host habitat influences intracellular phage biology. The overall high prevalence within the host population shows that filamentous phages can be an important component of the environmental biology of V. cholerae.
