Triple hop test distance, but not asymmetry, is associated with ankle sprains in elite adolescent volleyball players.

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
backgroundWe aimed to identify whether triple hop distance (THD) and asymmetry is associated with ankle injury in elite youth volleyballers.
methodA convenience sample of 100 elite youth male volleyball players (age 15.06 ± 0.87 years, height 178.74 ± 5.71 cm, and weight 68.38 ± 6.37 kg) were followed up in this prospective cohort study. Pre-season triple hop measures were obtained in 100 elite youth male volleyball players, and ankle injuries were tracked across the 6-month season. Logistic regression analysis was used to examine the relationship between triple hop distance and asymmetry and injury.
resultsEighteen ankle injuries occurred during season. Greater hop distances on the dominant (odds ratio [OR] = 0.28, 95% confidence intervals [CI] = 0.13 to 0.61, p = 0.001; moderate effect) and non-dominant (OR = 0.26, 95% CI = 0.12 to 0.56, p = 0.001; moderate effect) limbs were associated with a lower incidence of injury, as was greater height-normalized distances on the dominant (OR = 0.10, 95% CI = 0.02 to 0.40, p = 0.001; large effect) and non-dominant (OR = 0.08, 95% CI = 0.02 to 0.33, p = < 0.001; large effect) limbs. However, there was no significant association with triple hop test absolute or normalized asymmetry (OR = 1.18, 95% CI = 0.06 to 24.90, p = 0.915; trivial effect) or limb symmetry index (OR = 0.94, 95% CI = 0.87 to 1.01, p = 0.088; trivial effect) and injury risk.
conclusionLower THD are associated with future ankle injuries in elite volleyballers. The THD potentially offers a simple, reliable, and effective screening tool that can be used in volleyball to identify players at a greater risk of injury before the season commences.
