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

High-frequency acoustic wave transducers, favored for their compact size, are not only dominating mobile handsets but are also expanding into various interdisciplinary fields. However, as strong vibration can "shake off" substances and produce heat, a long-standing bottleneck has been the ability to harness acoustics under high-power loads, especially for interdigital-transducer-based surface acoustic wave devices. To suppress three fundamental mechanisms: self-heating, thermal instability, and acoustomigration, we propose a layered acoustic wave platform utilizing a quasi-infinite multifunctional top layer that redefines mechanical and thermal boundary conditions. The proposed transducer achieves a 70% reduction in temperature rise, a temperature coefficient of frequency of -13 ppm/°C, and an unprecedented threshold power density of 45.61 dBm/mm
