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
backgroundThe purpose of this study was to identify biomechanical patterns that determine the efficiency and stability of performing defensive movements in highly qualified boxers, and to establish relationships between the level of athletic training and the nature of motor strategies.
methodsThe study was conducted at the National Boxing Training Centre in Xianyang, Shaanxi Province, China, from January to December 2023. 28 athletes took part in the experiment, divided into two groups according to the level of competitive experience. The methodology included the recording of spatiotemporal, kinematic, kinetic, and electromyographic parameters when slipping, ducking, and performing sidesteps under conditions that simulated real combat.
resultsThe results showed that international boxers had a high amplitude and speed of movement of the centre of mass (CM) (by 12.3% and 18.6% higher), increased angular velocity in the hip joints (by 23.2°/s), and increased muscle activation of key segments of the torso and limbs (up to + 22.8%). There were more compact and reproducible patterns of muscle activity, a lower delay in peaks of effort (-22 ms), a decrease in peak moments of force in the joints (up to -16.5%), high load symmetry (89.2%) and reduced coefficients of variability, indicating the stability of the motor programme. National-level boxers have pronounced asymmetries, high inter-repetition variability, and slower reactive responses, which theoretically may increase biomechanical strain.
conclusionThe findings emphasise that biomechanical maturity, expressed in stable intermuscular coordination, symmetry and variability, is closely related to the competitive level. The practical significance lies in the use of these parameters for biomechanical monitoring, personalisation of the training process, and early detection of functional limitations that can affect the reliability and mechanical efficiency of the technique in combat conditions.
