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
Soft robotic grippers are capable of handling objects with diverse shapes and sizes. However, achieving reliable grasping of delicate objects and sustaining prolonged holding with minimal energy input remains challenging. This study reports a miniaturized liquid crystal elastomer (LCE) soft gripper featuring a kirigami-inspired architecture, which is effective for capturing and securing delicate and slippery objects. The gripper consists of an LCE kirigami structure, which serves as the active material for generating deformation, and a conductive composite layer (CCL), which serves as a piezoresistive material for detecting deformations. In addition, the gripper opens its fingers when actuated, and closes its fingers for gripping objects when unactuated. Therefore, the device does not require any power when continuously holding objects. The gripper is also capable of detecting grasped object sizes enabled by the CCL. Demonstrations of grasping objects of various shapes, materials, and weights were also provided.
