High molecular diversity and divergent subpopulations of the begomovirus cnidoscolus mosaic leaf deformation virus associated with Cnidoscolus urens.
Article in Archives of virology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Begomoviruses have circular, single-stranded DNA genomes encapsidated into twinned quasi-icosahedral particles and are transmitted by whiteflies of the Bemisia tabaci sibling group. Begomoviruses infect cultivated and non-cultivated plants, causing great losses in economically important crops worldwide. To better understand the genetic diversity of begomoviruses infecting the non-cultivated host Cnidoscolus urens, leaf samples exhibiting virus-like symptoms were collected in different localities in the state of Alagoas, Brazil, during 2015 and 2016. Forty-two complete DNA-A sequences were cloned and sequenced by the Sanger method. Based on nucleotide sequence comparisons, the 42 new isolates were identified as the bipartite begomovirus cnidoscolus mosaic leaf deformation virus (CnMLDV). The CnMLDV isolates were clustered in two phylogenetic groups (clusters I and II) corresponding to their sampling areas, and the high value of Wright's F fixation index observed for the DNA-A sequences suggests population structuring. At least seven independent intraspecies recombination events were predicted among CnMLDV isolates, with recombination breakpoints located in the common region (CR) and in the CP and Rep genes. Also, a high per site nucleotide diversity (π) was observed for CnMLDV isolates, with CP being significantly more variable than Rep. Despite the high genetic variability, strong negative or purifying selection was identified as the main selective force acting upon CP and Rep.
