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.
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
In this study, we propose a far-field wireless power transmission system utilizing a mobile laser steering module (MOLASM) for optogenetic applications. The system integrates a MEMS-based active micromirror and features a battery-free architecture, enabling a miniaturized, lightweight, and mobile operation. This design allows for precise laser steering while maintaining a compact form factor. Additionally, laser superimposition using multiple MOLASMs enhances wirelessly transmitted power, ensuring scalable and adaptable` energy delivery for diverse experimental needs. High-efficiency photovoltaic module harvests energy from precisely targeted laser beams emitted from MOLASM, enabling continuous, wire-free operation without the need for external recharging or replacement. To validate the feasibility of this concept, we designed, implemented, and experimentally evaluated the dynamic beam steering and power delivery performance of the MOLASM system. The results demonstrate its effectiveness in wirelessly powering optogenetic probes over far-field distances, providing a flexible and practical solution for neuromodulation studies.
