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

Spider silk featuring strength-toughness synergy and rapid stimuli-responsiveness has inspired efforts to synthesize multifunctional fibers for advanced applications in soft robotics. However, replicating these incompatible properties remains hindered by the inadequate structural design which fails to integrate the rigid components and reversible interactions into a single system. Herein, we fabricate tough and responsive contractile ionogel fibers by nanoconfinement entanglement-enhanced phase separation strategy based on the bottlebrush-shaped composite slurry. The programmed assembly enables the multiscale energy dissipation, while efficient stress transfer and entanglement endow high network entropy elasticity and stable network integrity under hydration. Consequently, the produced fibers present an high tensile toughness of 1652.2 MJ · m
