Epidemiology of ankle sprains and anterior cruciate ligament injuries in youth basketball athletes in Niigata, Japan: A regional survey on injury management and healthcare professional involvement.
Article in PloS one, 2026. 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
objectiveAnkle sprains are highly prevalent among youth basketball players, particularly in the under-15 age group, and inadequate post-injury management may contribute to the development of chronic ankle instability and may be associated with an increased risk of anterior cruciate ligament injuries. This study aimed to determine the incidence of ankle sprains and post-injury management among under-12 and under-15 basketball players through a large-scale questionnaire survey. Additionally, we examined the prevalence of chronic ankle instability and anterior cruciate ligament injuries to assess the epidemiological impact of ankle sprains on young athletes. By examining these age groups, this study aimed to provide insights into potential preventive strategies and the need for appropriate medical intervention during early athletic development.
methodsA cross-sectional survey was conducted to assess ankle sprain history, medical consultation rates, prevalence of chronic ankle instability, and anterior cruciate ligament injuries. The study targeted school and club basketball teams in Niigata, Japan. Overall, 2,747 youth basketball players from under-12 and under-15 age groups participated.
resultsAnkle sprains were more common in under-15 players (61.2%) than in under-12 players (39.0%). Medical consultation rates were lower in under-15 players (56.6%) than in under-12 players (80.1%). Chronic ankle instability was found in 12.4% of the players. Among under-15 players, 0.9% underwent anterior cruciate ligament reconstruction, and half of them had chronic ankle instability. Many players returned to play despite experiencing pain.
conclusionsThe coexistence of chronic ankle instability and anterior cruciate ligament injuries suggests a possible association between these conditions; however, causal relationships cannot be inferred because of the cross-sectional study design and the small number of anterior cruciate ligament cases.
