Discrete Symmetry Metrics Mask Frequent Phase-Specific Lower Limb Asymmetry During Bilateral Countermovement Jumping in Youth Football Players.

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
Inter-limb asymmetry is frequently evaluated during bilateral tasks such as the countermovement jump (CMJ), typically using discrete peak-based metrics. However, these approaches may inadequately capture the complex, time-varying nature of inter-limb coordination. This study examined inter-limb asymmetry during CMJ in youth football players using both discrete and continuous assessments, with consideration of limb dominance. Forty-three male youth academy football players (14 ± 1.1 years) performed three maximal bilateral CMJs with data collected using dual force platforms and three-dimensional motion capture. Inter-limb asymmetry was quantified using discrete symmetry indices for peak vertical ground reaction force (GRF
