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

Mycoplasma agalactiae causes one of the most serious forms of mycoplasmosis in small ruminants that is notifiable to the World Organization for Animal Health (WOAH). Possessing a plastic genome, its Vpma and other surface antigenic variations play important roles in its pathogenesis and systemic spread within the goat or sheep host, as well as its ability to jump to wild animals. The Vpma phenotypic profile of strain GM139 was recently compared to that of the type strain PG2, whereby GM139 predominantly exhibited stable expression of a single VpmaV protein in comparison with the high-frequency variable expression of all six Vpma proteins in PG2. The complete genome sequence of GM139 was generated, annotated for detailed analysis of the vpma locus and compared with the finished genomes of three distinct M. agalactiae strains (PG2, 5632, and GrTh01). Interestingly, GM139 presented a longer distinct vpma locus with ten genes, one of which is a chimera between the vpmaV and vpmaZ genes of PG2, which correlates very well with previous immunoblotting results and was confirmed here by nanoLC-MS/MS analysis; five vpmas are completely unique, whereas the other four share similarities with the vpmas of 5632, one of which is also partially homologous to vpmaZ
