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 recombination is one of the most frequently identified drivers of double-stranded DNA viruses evolution. However, the recombination events in African swine fever virus (ASFV) genomes have been poorly annotated. We hypothesize that the genetic determinants of ASFV variability are potential hot-spots for recombination. Here, we analyzed ASFV serotype-specific locus (C-type lectin (EP153R) and CD2v (EP402R)) in order to allocate the recombination breakpoints in these immunologically important proteins and reveal driving forces of virus evolution. The recombinations were found in both proteins, mostly among ASFV strains from East Africa, where multiple virus transmission cycles are notified. The recombination events were essentially associated with the domain organization of proteins. The phylogenetic analysis demonstrated the lack of clonal evolution for African strains which conclusively support the significance of recombinations in the serotype-specific locus. In addition, the signature of adaptive evolution of these two genes, pN/pS > 1, was demonstrated. These results have implications for the interpretation of cross-protection potential between evolutionary distant ASFV strains and strongly suggest that C-type lectin and CD2v may experience substantial selective pressure than previously thought.
