The Association of Body Mass Index and Achilles Tendon Rupture: A Retrospective Case-Control Study.
Article in Foot & ankle orthopaedics, 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: Achilles tendon rupture (ATR) is a common injury with an estimated incidence of about 7 to 40 per 100,000 person-years. Identifying risk factors for ATR is an important step toward injury prevention. Modifiable factors, such as body mass index (BMI), are of particular interest because of the potential for intervention, and recent studies have shown mixed results for BMI as a risk factor for ATR. This case-control study aims to compare the BMI of patients diagnosed with a primary ATR to age and sex-matched controls diagnosed with an ankle sprain. Methods: A retrospective chart review of 168 patients was performed, which included 56 patients with ATR age- and sex-matched with 112 ankle sprain controls. Demographics and BMI data were collected and compared across the 2 groups. Mann-Whitney Results: The mean BMI for ATR was 33.4 and ankle sprain was 31.9, which was not statistically significant ( Conclusion: This study found that a BMI between 18 and 25 was associated with lower rates of ATR when compared to BMI classes greater than 25. Our data suggests that BMI may be an independent factor associated with ATR, even in patients engaging in sporting activity. Level of Evidence: Level III, case-control study.
