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

The low-Ca2+-response (LCR) plasmid pCD1 of the plague agent Yersinia pestis KIM5 was sequenced and analyzed for its genetic structure. pCD1 (70,509 bp) has an IncFIIA-like replicon and a SopABC-like partition region. We have assigned 60 apparently intact open reading frames (ORFs) that are not contained within transposable elements. Of these, 47 are proven or possible members of the LCR, a major virulence property of human-pathogenic Yersinia spp., that had been identified previously in one or more of Y. pestis or the enteropathogenic yersiniae Yersinia enterocolitica and Yersinia pseudotuberculosis. Of these 47 LCR-related ORFs, 35 constitute a continuous LCR cluster. The other LCR-related ORFs are interspersed among three intact insertion sequence (IS) elements (IS100 and two new IS elements, IS1616 and IS1617) and numerous defective or partial transposable elements. Regional variations in percent GC content and among ORFs encoding effector proteins of the LCR are additional evidence of a complex history for this plasmid. Our analysis suggested the possible addition of a new Syc- and Yop-encoding operon to the LCR-related pCD1 genes and gave no support for the existence of YopL. YadA likely is not expressed, as was the case for Y. pestis EV76, and the gene for the lipoprotein YlpA found in Y. enterocolitica likely is a pseudogene in Y. pestis. The yopM gene is longer than previously thought (by a sequence encoding two leucine-rich repeats), the ORF upstream of ypkA-yopJ is discussed as a potential Syc gene, and a previously undescribed ORF downstream of yopE was identified as being potentially significant. Eight other ORFs not associated with IS elements were identified and deserve future investigation into their functions.
