The Relationship Between Hand Dominance and ACL Tears in Competitive Volleyball Athletes.

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
Background: Knee injuries are common in volleyball athletes, often resulting from the sport's unique movement requirements. Among these, anterior cruciate ligament (ACL) tears are particularly prevalent, and while the existing literature has examined risk factors such as biomechanical asymmetries and landing mechanics, there is limited research on the relationship between hand dominance and the side of injury. Purpose: To examine the relationship between hand dominance and ACL tear laterality in competitive volleyball players diagnosed with first-time unilateral ACL tears. Study Design: Cross-sectional study; Level of evidence, 3. Methods: After a medical record review of 1529 consecutive patients, 149 met the inclusion criteria, resulting in a study population of 124 females and 25 males. Data on sex, age, body mass index, handedness, and ACL tear laterality were collected from the medical records. A Fisher exact test was used to assess the association between handedness and ACL tear laterality, while binomial tests evaluated differences in ACL tear laterality within each handedness group. Results: Among the 136 right-handed players, 81.62% tore their left ACL, while 18.38% tore their right ACL. Among the 13 left-handed players, 84.62% tore their right ACL, while 15.38% tore their left ACL. A statistically significant association was found between hand dominance and ACL tear laterality ( Conclusion: This study suggests a significant relationship between hand dominance and ACL tear laterality in competitive volleyball players. Right-handed volleyball players were significantly more likely to tear their left ACL, whereas left-handed players predominantly tore their right ACL. These findings suggest a biomechanical or sports-specific risk factor contributing to ACL injury patterns in volleyball players.
