Stress fracture risk factors in soccer players: A systematic review.
Review in Annals of medicine and surgery (2012), 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: This study conducted a systematic review to evaluate stress fracture risk factors in soccer players, aiming to enhance injury prevention strategies. Methods: We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, focusing on professional soccer players. Database searches (Medline, Scopus, CENTRAL, Embase, and Web of Science) used predefined terms in November 2024. Bias assessment employed Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument tools, and descriptive synthesis was used due to limited meta-analyzable data. Results: Our systematic review analyzed 26 studies with 8514 participants. Young age was a risk factor in four studies, and female gender in one. High body mass index, increased training hours, competitions, and intense preseason training also raised risk. Anatomical factors included lower calcaneal pitch angle, wider medial malleolar slip angle, higher Talocalcaneal angle, and lower limb varus malalignment. Stress fractures were higher among midfielders in one study, while two others found no positional differences. Additional risks were elevated parathyroid hormone, higher bone-specific alkaline phosphatase, lower 25OH levels, fasting, and perceived stress from negative life events. Conclusions: Soccer players face a heightened risk of stress fractures due to the repetitive forces involved in the sport, a significant concern given its global popularity. Although this review identified several risk factors, ongoing controversies remain, primarily due to the limited number of studies and the complex, multifactorial nature of stress fractures.
