1 · What the graph read from it

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.

2 · The registry

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

For the first time, dynamic covalent networks are prepared that show spontaneous alignment and long-range hexagonal columnar ordering. This is a consequence of the phase-separation between the siloxane linkers and dynamic covalent acylsemicarbazide bonds that induce hydrogen bonding. The use of discrete siloxane linkers is crucial, as networks based on disperse siloxanes do not give ordered or aligned network structures. Optimization of the siloxane length is key in achieving the most pronounced effect. Interestingly, the optimized ordered networks are obtained through simple solvent evaporation, allowing to introduce near-perfect homeotropic alignment as imaged with transmission electron microscopy and corroborated with grazing incidence small angle x-ray scattering. The ordered network has improved (thermo)mechanical properties compared to the disordered networks. Additionally, order in the system slows down the network dynamics and improves creep resistance. We prepare actuators in a straightforward fashion by combining ordered and disordered networks, removing the need for any alignment step and simplifying the overall process significantly.
