Unusual ultrastructures of the Branchiostoma IF protein C2 containing heptads in the tail.
Article in Protoplasma, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Branchiostoma intermediate filament (IF) protein C2 contains a long tail domain consisting of several degenerate repeats which display a heptad repeat pattern. This unique tail sequence is predicted to constitute a long coiled coil domain in C2, which is separated from the rod by a glycine-rich linker L3. The recombinant IF protein C2 shows, in electron microscopy (EM), parallel rodlike dimers of 66.7 nm decorated by a larger globule on one side and a smaller globule on the other side. In contrast, the length of the tailless C2 dimers, decorated by only one small globule, is about 26 nm shorter. These results indicate that both the rod domain and the newly predicted coiled coil segment 3 participate in the formation of a double-stranded coiled coil dimer. Moreover, the two to four C2 dimers are able to associate via their globular tail domain into multiarm oligomers, an ability not seen by the tailless C2 mutant or the other currently known protostomic and vertebrate IFs.
