Preventive Effect of Cross-motion Swing Exercise on Groin Pain in High School Male Soccer Players: A Cluster Randomized Controlled Trial.
Article in Orthopaedic journal of sports medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Groin pain in soccer players arises from various causes, most commonly kicking, and as such can significantly affect performance. A new form of exercise, the cross-motion swing exercise (CMS), may help prevent groin pain but is untested. Purpose: To evaluate the effectiveness of the CMS in preventing groin pain in high school soccer players. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: This study involved 135 male high school soccer players <18 years from 4 teams competing in a high school soccer league in Japan. Teams were randomly assigned to an intervention group (2 teams; n = 65 players) or a control group (2 teams; n = 70 players). The intervention group performed the CMS in addition to their usual warm-up, emphasizing coordination and kicking movements, while the control group continued their usual warm-up exercise. The intervention period lasted 16 weeks, with compliance monitored weekly. Data were collected through weekly Google form surveys. The primary outcome was the incidence of groin pain at any time during the study period. Results: The intervention group had a significantly lower incidence of groin pain (9.4%) compared with the control group (23.1%). Cox proportional hazards regression analysis indicated a significantly reduced risk of groin pain in the intervention group (hazard ratio, 0.309; 95% CI, 0.108-0.880; Conclusion: The CMS significantly reduced the incidence of groin pain in high school soccer players. This suggests that coordination-based exercise, closely mimicking the appropriate sports-specific movement, was effective in reducing injury. The study supports incorporating the CMS into regular training to reduce the incidence of groin pain in male high school soccer players. Trial Registry and the Registration Number: This study has been registered as a clinical trial with the Universal Medical Information Network (UMIN) under the registration number UMIN000051311.
