Molecular adaptation in the ice worm, Mesenchytraeus solifugus: divergence of energetic-associated genes.
Article in Journal of molecular evolution, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 ice worm, Mesenchytraeus solifugus, is the largest glacially obligate metazoan and among only a few metazoan species that complete their life cycle at 0 degrees C. We conducted a large-scale sequencing analysis of cDNAs isolated from ice worm anterior segments. Sequence comparisons among an available group of ice worm, arthropod, chordate, and nematode homologues suggest that ice worms encode proteins that are less bulky, are less polar, and contain fewer charged residues. Also, subunits of the catalytic F1 ATP synthase complex appear to have diverged more rapidly than other ice worm genes examined, suggesting a role in cold-temperature adaptation. Modeling of F1 ATP synthase beta and gamma subunits identified nonconservative, ice worm-specific amino acid substitutions at subunit contact sites and at sites proximal to the catalytic site.
