Evolutionary loss and replacement of Buchnera, the obligate endosymbiont of aphids.
Article in The ISME journal, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 48 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
Symbiotic interactions between organisms create new ecological niches. For example, many insects survive on plant-sap with the aid of maternally transmitted bacterial symbionts that provision essential nutrients lacking in this diet. Symbiotic partners often enter a long-term relationship in which the co-evolutionary fate of lineages is interdependent. Obligate symbionts that are strictly maternally transmitted experience genetic drift and genome degradation, compromising symbiont function and reducing host fitness unless hosts can compensate for these deficits. One evolutionary solution is the acquisition of a novel symbiont with a functionally intact genome. Whereas almost all aphids host the anciently acquired bacterial endosymbiont Buchnera aphidicola (Gammaproteobacteria), Geopemphigus species have lost Buchnera and instead contain a maternally transmitted symbiont closely related to several known insect symbionts from the bacterial phylum Bacteroidetes. A complete genome sequence shows the symbiont has lost many ancestral genes, resulting in a genome size intermediate between that of free-living and symbiotic Bacteroidetes. The Geopemphigus symbiont retains biosynthetic pathways for amino acids and vitamins, as in Buchnera and other insect symbionts. This case of evolutionary replacement of Buchnera provides an opportunity to further understand the evolution and functional genomics of symbiosis.
