Differential expression of a sodium-phosphate cotransporter among Vibrio vulnificus strains.
Article in Microbial ecology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Vibrio vulnificus is an estuarine bacterium with pathogenic potential. Its three known biotypes differ in host distribution. We have found the nptA gene for a sodium-phosphate cotransporter, which is rare in bacteria, in each biotype. nptA transcript abundance differed significantly among biotypes, leading to the hypothesis that transcript levels differ under environmental conditions associated with estuarine and host environments. nptA transcript abundance was assessed in V. vulnificus biotypes 1 (C and E genotypes), 2 and 3 strains under varied salinity, phosphate concentration, and pH. Differences in transcript abundance separated strains into two groups. Type C and biotype 3 strains formed Group 1, while type E and biotype 2 strains formed Group 2. Group 2 strains had significantly greater nptA RNA transcript abundance than Group 1. Transcript abundance in the two groups also responded differently to pH and salinity, suggesting differential regulation of nptA in response to environmental conditions. Comparison of the deduced amino acid sequences of NptA among strains resulted in strain grouping similar to that based on transcript abundance. Variation in transcript abundance between groups may affect the ability of V. vulnificus strains to colonize hosts and/or to compete as free-living bacteria in various habitats.
