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
Developing versatile insect-scale robots that can handle various unstructured scenarios with a simple design remains a critical challenge. Here, we introduce a single electromagnetic actuator-driven insect-scale robot, developed by integrating geometric and mass asymmetries into a deformable hexagonal frame. This asymmetric configuration induces nonlinear dynamic behaviors in the robot, allowing it to perform a variety of complex actions (e.g., forward and backward locomotion, active flipping, and lateral movement) and respond to challenging scenarios (e.g., granular media and safe landing) through posture transitions. To facilitate the behavior modulation and design optimization of the proposed insect-scale robot, a nonlinear dynamic model is established to map the relationship between motion behaviors and input parameters. Last, an untethered prototype that can work in outdoor environments is constructed to further demonstrate the practical applications.
