Change-of-direction ability in soccer is angle-specific: implications for multi-angle testing and speed deficit calculation.

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
The ability to change direction is crucial in soccer due to the high frequency of rapid movement adjustments during match play. This study examined the effects of change-of-direction (COD) angle (45°, 90°, 180°) and limb dominance on sprint speed in 18 experienced male soccer players using a multi-angle fieldbased assessment. Athletes completed a 20 m linear sprint and three 20 m COD sprints, each incorporating a single directional change at 15 m. Mean speed was assessed across the 0-10 m, 10-20 m (COD speed), 10-13 m (entry speed), and 13-20 m segments, and percentage COD speed deficit relative to linear sprinting (%CODD) was calculated. Mean speed in the 0-10 m segment was identical between linear and COD sprints (5.18 ± 0.28 to 5.28 ± 0.28 m · s
