Structures and formation mechanisms of aquo/hydroxo oligomeric beryllium in aqueous solution: a density functional theory study.

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 structures and formation mechanisms of a wide variety of aquo/hydroxo oligomeric beryllium clusters were investigated using density functional theory. The structural parameters of beryllium clusters were found to vary regularly with the stepwise substitution of bound water molecules in the inner coordination sphere by hydroxyl groups. According to the Gibbs free energies deduced from SMD solvation model computations, unhydrolyzed oligomeric beryllium species are the most favorable products of polymerization, independent of the degrees of hydrolysis of the reactants. Simulation of the formation processes of oligomeric beryllium showed that polymerization, in essence, involves the nucleophilic attack of a terminal hydroxyl group in one BeO4 tetrahedron on the beryllium center in another BeO4 tetrahedron, leading to the bridging of two BeO4 tetrahedrons by a hydroxyl group.
