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

Conjugated polymers (CPs) show great potential for pressure detection due to the amorphous polymer packing, but a lack of clarity regarding sensing mechanisms hampers the development of further applications. Herein, a sacrificial template-full solution method with both rough surface and high conductivity is described that can be applied to sandwich-structured resistive pressure sensors. Transient absorption measurements demonstrate the significant increase of carrier lifetime (from 1.44 to 2.54 ns) induced by pressure, which directly evidenced the superior sensing mechanism of sidechain doped conjugated polymer. This sensor displayed low-pressure detection limit of 0.7 Pa as well as a rapid response time of 18.8 ms, enabling multi-mode motion analysis including wrist pulse, swallowing, finger bending, grabbing, and typing. Additionally, an intelligent vocal recognition system with convolutional neural networks is used which can achieve >96% classification accuracy across diverse vocal profiles. This general approach is anticipated and enables a new direction for the development of pressure sensors.
