Amino acid exchangeabilities vary across the tree of life.
Article in Science advances, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Different amino acid pairs have drastically different relative exchangeabilities (REs), and accounting for this variation is an important and common practice in inferring phylogenies, testing selection, and predicting mutational effects, among other analyses. In all such endeavors, REs have been generally considered invariant among species; this assumption, however, has not been scrutinized. Using maximum likelihood to analyze 180 genome sequences, we estimated REs from 90 clades representing all three domains of life, and found numerous instances of substantial between-clade differences in REs. REs show more differences between orthologous proteins of different clades than unrelated proteins of the same clade, suggesting that REs are genome-wide, clade-specific features, probably a result of proteome-wide evolutionary changes in the physicochemical environments of amino acid residues. The discovery of among-clade RE variations cautions against assuming constant REs in various analyses and demonstrates a higher-than-expected complexity in mechanisms of proteome evolution.
