A molecular simulation study of the protection of insulin bioactive structure by trehalose.
Article in Journal of molecular modeling, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Biopharmaceuticals are proteins with a crucial role in the treatment of many diseases. However, these protein medicines are often thermally labile and therefore unsuitable for long-term application and storage, as they tend to lose their activity under ambient conditions. Desiccation is one approach to improving protein stability, but the drying process itself can cause irreversible damage. In the current study, insulin was chosen as an example of a thermally sensitive biopharmaceutical to investigate whether the disaccharide, trehalose, can prevent loss of structural integrity due to drying. The experiment was performed using replica exchange molecular simulation and Gromacs software with a Gromos96 (53a6) force field. The results indicate that trehalose preserves the bioactive structure of insulin during drying, consistent with the use of trehalose as a protectant for thermally sensitive biopharmaceuticals. For instance, at the water content of 1.77%, insulin without any protectants yields the highest RMSD value as 0.451 nm, then the RMSD of insulin in presence of trehalose only ca. 0.100 nm.
