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
Running-specific prostheses (RSPs) enable individuals with lower-limb amputation to compete in Paralympic running disciplines. In a high-level sports context, optimal RSP tuning based on biomechanical parameters is essential to enhance running performance. Although on-track assessment is considered the gold standard, its high financial and logistical demands make treadmill-based setups valuable alternatives. Therefore, this single-case study aimed to present a method for assessing steady-state running (SSR) and resisted acceleration running (RAR) in an amputee athlete, comparing different RSP alignments. The experimental setup combined a commercial treadmill mounted over four dynamometric platforms with an eight-camera motion capture system, enabling the kinetic, kinematic, and spatiotemporal assessment of different RSP configurations. Differences in biomechanical parameters were observed between RSP configurations during both SSR and RAR, including variations in GRFs and corresponding impulses, as well as hip, knee, and ankle kinematics. However, the sensitivity of the proposed method in detecting biomechanical differences should be interpreted with caution, as it is based on a single Paralympic athlete. In conclusion, these findings suggest that the treadmill-based protocol may serve as a functional and controlled screening tool for preliminary performance-oriented RSP tuning, enabling the identification of promising configurations prior to definitive assessments on an instrumented athletics track.
