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
Steered molecular dynamics simulations of the mechanosensitive channel of large conductance, MscL, were used to investigate how forces arising from membrane tension induce gating of the channel. A homology model of the closed form of MscL from Escherichia coli was subjected to external forces of 35-70 pN applied to residues near the membrane-water interface. The magnitude and location of these forces corresponded to those determined from the lateral pressure profile computed from a lipid bilayer simulation. A fully expanded state was obtained on the 10-ns timescale that revealed the mechanism for transducing membrane forces into channel opening. The expanded state agrees well with proposed models of MscL gating, in that it entails an irislike expansion of the pore accompanied by tilting of the transmembrane helices. The channel was most easily opened when force was applied predominantly on the cytoplasmic side of MscL. Comparison of simulations in which gating progressed to varying degrees identified residues that pose steric hindrance to channel opening.
