The bacterial mechanosensitive channel MscM gates through concerted changes in its transmembrane and cytoplasmic domains.

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 mechanosensitive channel of small conductance (MscS) is the founding member of the family of MscS-like channels, which share a structurally conserved core but feature additional structural elements that define their specific channel characteristics. Here, we characterize the structure and function of the Escherichia coli mechanosensitive channel of mini conductance (MscM), which features eight additional transmembrane (TM) helices and a large periplasmic domain. Our cryo-EM structures reveal that channel gating involves conformational changes in all domains of MscM. In particular, a cytoplasmic extension of TM7 couples the conformation of the TM domain to that of the cytoplasmic domain, resulting in gating of its lateral fenestrations, where ions enter the channel. Thus, different from all other MscS-like channels studied to date, channel gating in MscM is mediated by its cytoplasmic domain and not the TM domain, which senses changes in membrane tension and operates the cytoplasmic gates.
