1 · What the graph read from it

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.

2 · The registry

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

purposeThis study explores the relationship among lower limb dynamic balance, lower limb strength, explosive power, agility, and sports injuries in male volleyball players.

methodThe study involved thirty-one male volleyball athletes assessed for lower limb dynamic balance using the Y Balance Test Kit™. Muscle strength in the hip, knee, and ankle was measured using the Isomed 2000 isokinetic dynamometer. Power performance was evaluated through squat jump, countermovement (CMJ) jump, and drop jump tests using the Kistler force platform. Agility measurements were conducted using timing gates and a stopwatch.

resultsOur findings revealed a significant correlation between interlimb asymmetry in the anterior reach of the Y balance test and non-contact injuries (r = 0.597, P < 0.01). Additionally, there were significant correlations between the Y balance test and lower limb strength (r = 0.356 to 0.715, P < 0.05), vertical jumping performance (r = 0.357 to 0.672, P < 0.05), and agility (r = -0.379 to -0.702, P < 0.05).

conclusionBased on these findings, It is recommended that interlimb asymmetry in the anterior reach direction of the Y Balance Test be considered as one of the indicators for potential non-contact lower limb injuries among elite male volleyball players. The lower limb muscle strength of the hip, knee, and ankle joints and power and agility are associated with lower limb dynamic balance capabilities. Additionally, dynamic balance may contribute to overall physical performance. Targeted strength training for unilateral muscles and incorporating various explosive exercise modes may support athletic performance and reduce the risk of sports-related injuries.
