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
backgroundAcceleration, short-distance sprinting, and rapid change-of-direction are critical performance determinants in handball. This study examined the associations between key lower-limb performance indicators and sprint/reactive agility outcomes and evaluated their independent associations within multivariable models in elite female handball players.
methodsTwenty-seven athletes (n = 27; age 15.61 ± 0.69 years) completed assessments of countermovement jump (CMJ), squat jump (SJ), reactive strength index (RSI_{3–5}), leg stiffness, and relative power; sprint performance (0–5–10–20 m) and reactive agility were evaluated using standardized field protocols. Pairwise relationships were analysed using Pearson’s correlations, and independent contributions were evaluated with AIC-guided multivariable linear regression (standardized β, adjusted R²).
resultsStrong associations were observed between CMJ/RSI and sprint/agility parameters (r = 0.65–0.89, p < 0.01). In regression models, RSI and leg stiffness were retained as significant associated variables, particularly in relation to the 5–20 m sprint segments and reactive agility (standardized β = 0.31–0.67). The models showed high explanatory capacity for sprint outcomes, reaching an adjusted R² of 0.825 in the 5–10 m sprint model, and more moderate explanatory capacity for agility outcomes (adj. R² = 0.422).
conclusionsThese findings indicate that jump-derived elastic/neuromuscular indices, particularly RSI and leg stiffness, are independently associated with sprint and reactive agility performance in elite female handball players. However, given the cross-sectional design, these associations should not be interpreted causally. The results may help identify candidate performance-monitoring variables for practice settings. Prospective and intervention-based studies are required to determine whether modifying these variables improves sprint or agility outcomes.
