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

Ultrasonic power and data transfer is a promising technology for implantable medical devices because of its non-invasiveness, deep penetration depth, and potential for a high-power transmission rate with a low specific absorption rate. However, ultrasound-powered implantable devices still suffer from low power transfer efficiency due to beam misalignment and are limited to short-term use due to the bulkiness of the transmitting transducers. Here, we report the first proof of concept for adaptive positioning and targeting of ultrasound-based implantable devices through ultrasound image guidance. A lightweight patch-type ultrasonic transducer array is fabricated to enable ultrasound imaging and beam-forming during long-term operation. The uniform performance of the array is established through the silicon micromachining process. We demonstrate the complete scheme of imaging, positioning, and targeted power transfer in an ex vivo environment, achieving precise targeting of moving implanted devices through real-time ultrasound imaging. Enhanced power transfer efficiency through the use of patch-type ultrasonic transducers can enhance patient comfort and minimize invasive procedures, opening new applications for ultrasonic-powered implantable devices.
