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
backgroundThis study examines the hierarchical determinants of change-of-direction (COD) ability in adolescent athletes to assess whether sprint performance functions as a potential intermediate variable of the relationship between explosive power and COD performance.
methodsThe study recruited 86 high school athlete participants. Explosive power was assessed using the countermovement jump (CMJ) and squat jump (SJ). Sprint performance was evaluated using 10 m and 20 m sprint tests. COD performance was assessed using the 505 pre-planned COD test. Body composition was also recorded.
resultsCorrelation analyses indicates that 20 m sprint time was positively associated with COD performance (r = 0.67-0.82), whereas CMJ performance was significantly and negatively associated with COD performance (r = -0.65 to -0.68). Multiple regression analysis explained 63.6% of the variance in COD performance; sprint performance emerged as the strongest predictor. Indirect effect analysis showed that the effect of explosive power on COD performance is consistent with an indirect pathway by sprint performance. Structural equation modeling supported a hierarchical model: Explosive power was associated with sprint performance, which in turn was associated with COD ability.
conclusionsThe findings suggest that improvements in COD performance among adolescent athletes may depend on enhancing explosive power while optimizing acceleration and speed-transfer capacity. These findings provide practical implications for athlete selection and training program design in youth sports.
