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
This paper presents the design, development, and validation of an innovative soft robotics-based elbow rehabilitation device. Unlike conventional rigid passive rehabilitators, the proposed system prioritizes safety in human-robot interaction while introducing a novel approach to enhancing elbow mobility. Functional tests were systematically conducted on pouch motors to assess their suitability for integration into the rehabilitator. The device achieved an elbow range of motion of 0°-90° and generated an optimal force of ~98 N at 2 bar of pressure. The experimental results revealed a distinct nonlinear performance behavior, which was thoroughly analyzed to refine system operation and modeling. The study establishes a comprehensive framework encompassing actuator manufacturing, experimental testing, dynamic system identification, and open-loop control validation. Collectively, these stages culminate in the validation of the proposed dynamic model. Overall, this work represents a meaningful advancement in rehabilitation technology, providing a safer and more adaptable alternative for elbow rehabilitation, with strong potential for application across diverse healthcare settings.
