In vivo measurement of protein functional changes.
Article in International journal of biological sciences, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Conformational changes in proteins are fundamental to all biological functions. In protein science, the concept of protein flexibility is widely used to describe protein dynamics and thermodynamic properties that control protein conformational changes. In this study, we show that urea, which has strong sedative potency, can be administered to fish at high concentrations, and that protein functional changes related to anesthesia induction can be measured in vivo. Ctenopharyngodon idellus (the grass carp) has two different types of N-methyl d-aspartate (NMDA) receptors, urea-insensitive and urea-sensitive, which are responsible for the heat endurance of fish. The urea-sensitive NMDA receptor showed high protein flexibility, the gamma aminobutyric acid (GABA) receptor showed less flexibility, and the protein that is responsible for ethanol anesthesia showed the lowest flexibility. The results suggest that an increase in protein flexibility underlies the fundamental biophysical mechanisms of volatile general anesthetics.
