Localization of HArep-containing genes on the chromosome of Porphyromonas gingivalis W83.
Article in Infection and immunity, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
We have mapped a group of virulence genes of Porphyromonas gingivalis to a single large fragment of the genome. These genes (rgpA, kgp, and hagA) all contain a consensus repeat sequence (HArep). rgpA and kgp encode cysteine proteases with Arg-X and Lys-X specificity, respectively, and hagA encodes a hemagglutinin. Genomic DNA fragments separated by pulse-field gel electrophoresis were blotted and probed in order to localize the genes to a 0.25-Mb NheI fragment of the P. gingivalis W83 genome. Further hybridization analyses with single- and double-restriction digestion allowed us to generate a physical map of the fragment and determine the precise locations of the protease and hemagglutinin genes. In addition, we found an insertion-like sequence, IS195, near the ends of the 0. 25-Mb NheI fragment. A similarly sized fragment carrying HArep sequences was also demonstrated in the P. gingivalis W12 and W50 genomes.
