Critical buckling length versus persistence length: what governs biofilament conformation?
Article in Physical review letters, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
We numerically study the length dependence in the bending stiffness of alpha helices, coiled coils, and a linear chain model. As the length approaches what we named the critical buckling length lc, the chain appears to become increasingly more flexible. This is due to weak nonbonded attractions that eventually lead to buckling instability and alter the chain's conformational ensemble. For alpha helices and coiled coils, lc is much less than their respective persistence lengths, so lc is the defining length scale for their conformations. These results elucidate the importance of weak nonspecific attractions that are inherent in many biofilaments in physiological conditions.
