Gene sequences of the pil operon reveal relationships between symbiotic strains of Vibrio fischeri.
Article in International journal of systematic and evolutionary microbiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Symbiosis between the bobtail squid Euprymna scolopes (Mollusca: Cephalopoda) and Vibrio fischeri bacteria has been a well-studied model for understanding the molecular mechanisms of colonization and adherence to host cells. For example, pilin expression has been observed to cause subtle variation in colonization for a number of Gram-negative bacteria with eukaryotic hosts. To investigate variation amongst pil genes of closely related strains of vibrios, we amplified pil genes A, B, C and D to determine orientation and sequence similarity to other symbiotic vibrios. The pilA gene was found to be upstream from all other pil genes, and not contiguous with the rest of the operon. The pilB, pilC and pilD loci were flanked at the 3' end by yacE, followed by a conserved hypothetical gene. DNA sequences of each pil gene were aligned and analysed phylogenetically using parsimony for both individual and combined gene trees. Results demonstrate that certain pil loci (pilB and pilD) are conserved among strains of V. fischeri, but pilC differs in sequence between symbiotic and free-living strains. Phylogenetic analysis of all pil genes gives better resolution of Indo-west Pacific V. fischeri symbionts compared with analysis of the 16S rRNA gene. Hawaiian and Australian symbiotic strains form one monophyletic tree, supporting the hypothesis that V. fischeri strain specificity is selected by the geographical location of their hosts and is not related to specific squid species.
