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 actuators capable of bending, twisting, and stretching have garnered significant interest for applications in wearable and mobile devices. In this study, we present the development of flexible linear stepping motors (FLSMs) with moving sliders fabricated from flexible printed circuit boards as thin as 0.1 mm. The force output of these motors can be enhanced by stacking multiple sliders, and their operational stroke length is theoretically unlimited. Experimental results demonstrate a maximum speed of 500 mm/s, a step size of 25 µm, and a force constant of 743 mN/A. Notably, the proposed device achieves the highest volumetric force constant of 5.94 mN/A(mm)
