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

Flexible and stable interconnections are critical for the next generation of shape-conformable and wearable electronics. These interconnections should have metal-like conductivity and sufficiently low stiffness that does not compromise the flexibility of the device; moreover, they must be achieved using low-temperature processes to prevent device damage. However, conventional interconnection bonding methods require additional adhesive layers, making it challenging to achieve these characteristics simultaneously. Here, we develop and characterize water vapor plasma–assisted bonding (WVPAB) that enables direct bonding of gold electrodes deposited on ultrathin polymer films. WVPAB bonds rough gold electrodes at room temperature and atmospheric pressure in ambient air. Hydroxyl groups generated by the plasma assist bonding between two gold surfaces, allowing the formation of a strong and stable interface. The applicability of WVPAB-mediated connections to ultrathin electronic systems was also demonstrated, and ultraflexible organic photovoltaics and light-emitting diodes fabricated on separate films were successfully interconnected via ultrathin wiring films.
