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

Electrocorticography electrode arrays (EEAs) are key brain-computer interfaces. To be freestanding, which lays the foundation of fabrication and implantation, EEAs need to maintain sufficient rigidity. However, to form seamless and damage-free contact on the cerebral cortex, EEAs should be super-flexible, raising a seemingly unsolvable dilemma. Here, inspired by dragonfly wings, we present a freestanding submicron EEA (fs-EEA) that combines rigidity and flexibility, which are typically mutually exclusive characteristics. A wing vein-like frame is introduced to enable the freestanding capability, while the wing membrane-like functional region of fs-EEA is reduced to 850-nm-thickness that boosts its softness. This fs-EEA ensures excellent cortical conformality and biocompatibility on male epileptic rat models, improves electrocorticographic amplitude and signal-to-noise ratio. Our vein-membrane hybrid structure strategy thus resolves the inherent contradiction of EEAs, and has the potential to support advances in brain science and related fields.
