Differences in knee-ankle configuration and ankle joint kinetic characteristics during a drop landing vertical jump task in highly trained male basketball players: a cross-sectional study based on rebound efficiency.

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
Objective: This study compared contact-phase timing, knee-ankle configuration at the lowest center of mass (COM), and ankle-moment characteristics between basketball players with high and low drop landing vertical jump (DLVJ) rebound efficiency. Methods: Forty-one highly trained male basketball players were classified as high ( Results: The high-efficiency group achieved greater DLVJ height ( Conclusion: Greater DLVJ rebound efficiency in highly trained basketball players was associated with shorter contact-phase durations, smaller knee flexion and ankle dorsiflexion at the lowest COM, and earlier ankle-moment timing during landing-to-repropulsion. These differences were not accompanied by higher relative maximal squat strength, suggesting that rebound efficiency reflects task-specific landing-transition characteristics rather than maximal lower-limb strength alone. Because contact time is included in the rebound-efficiency calculation, temporal findings should be interpreted as component characteristics, not independent outcomes. Knee-ankle configuration and ankle-moment timing may offer task-specific observational information on distal ankle-joint kinetic involvement during DLVJ performance.
