Correlations between insertional Achilles tendinopathy and haglund's deformity: MRI and radiographic findings.
Article in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe relationship between insertional Achilles tendinopathy (IAT) and Haglund's deformity has not been fully elucidated. This study aimed to determine the optimal cutoff value of MRI-based Achilles thickness and intratendinous degeneration for IAT and further explored the correlations of IAT and Haglund's deformity. MATERIALS AND
methodsThirty heels with symptomatic IAT (IAT group) underwent surgeries and 38 healthy participants without heel pain (control group) were enrolled. Five different radiographic parameters for diagnosing Haglund's deformity were measured. The IAT changes including tendon thickness and intratendinous degenerative ratio (ITD ratio) were obtained on MRI. The correlations of IAT and different radiographic parameters of Haglund's deformity were evaluated.
resultsA total of 68 feet were enrolled. The optimal thresholds of Achilles tendon thickness and ITD ratio were 6.1 mm and 48.8%, respectively. Both tendon thickness and ITD ratio were positively correlated with bump height and bump-calcaneus ratio (p < 0.001), but Fowler-Phillip angle, Heneghan-Pavlov parallel pitch lines and X-Y ratio were not.
conclusionAchilles tendon thickness of more than 6.1 mm and intratendinous abnormality of over 48.8% were confirmed to be diagnostic cutoff values for IAT. Haglund's deformity was determined as a risk factor of IAT requiring surgery. Both radiographic parameters of Haglund's deformity using the bump height and the bump-calcaneus ratio were useful in predicting the presence of IAT on MRI. LEVEL OF CLINICAL EVIDENCE: Level III, Retrospective cohort study.
