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 study provides a comparative kinematic analysis of futsal instep shot performance between trained athletes and novice players, addressing limited evidence on how multijoint kinematic patterns are associated with ball velocity. Twenty trained futsal athletes and twenty novice players performed standardized instep shots recorded using high-speed cameras at 240 fps. Research procedures included camera calibration, frame-by-frame motion analysis, reliability testing, and kinematic extraction using Dartfish software. Joint angles, angular velocities, torso orientation, and ball velocity were examined using independent-sample t-tests, effect sizes, and multiple regression analysis. Trained athletes exhibited more optimized multijoint kinematic patterns, characterized by more mechanically efficient knee positioning during foot placement and backswing, improved torso stability, and effective upper-limb positioning. Significant between-group differences were detected across most kinematic variables (p < 0.05). Knee angular velocity emerged as the strongest predictor of ball velocity (R² = 0.62, p < 0.01). Optimized lower- and upper-body kinematic patterns are associated with shooting proficiency and performance, supporting targeted technical training focused on optimizing shooting mechanics and kinematic efficiency.
