Re-evaluation of the evolution of influenza H1 viruses using direct PCA.
Article in Scientific reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The history of influenza H1 virus was re-evaluated by applying a new methodology to sequencing data; this objective method enables comparisons among viral types. The approach led to the segregation of all segments of swine and human viruses into three distinct groups: two of them included the pandemic 1977 and 2009 human viruses, and the remaining group may be new in humans. These three groups might have originated from avian viruses and drifted out independently. Genome shifts occurred occasionally among swine viruses; however, distances between avian and swine/human viruses negated the existence of direct shifts from avian viruses. In humans, only one or two viruses appeared each year, which suggests the presence of competition among viruses that migrated freely. All segments drifted continuously under certain rules and constant velocity. Viruses that had caused an outbreak did not appear again over subsequent decades, which may mean populations had become immune to such viruses. In contrast, the viruses in livestock were rather conserved and maintained unique strains in small, separate areas. Such collections of swine strains included human segments, which could become an epidemic in the future.
