Increased Risk of Fracture Among Patients With Iron Overload: A Population-based Matched Cohort Study.
Article in The Journal of clinical endocrinology and metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
introductionIron overloading disorders are associated with decreased bone mineral density. However, evidence on fracture risk is scarce. Therefore, we evaluated the risk of fracture associated with iron overload disorders compared to matched controls.
methodsUsing The Healthcare Improvement Network, a Cegedim database of UK general practice data, we identified patients >18 years with elevated iron (ferritin value >1000 µg/L) or an eligible diagnosis code for iron overloading disorders between 2010 and 2022. The first date of elevated iron or a diagnosis code defined the index date for iron overload patients, who were matched with up to 10 controls. Time-varying confounder-adjusted Cox proportional hazard models estimated the hazard ratios (HRs) and 95% confidence intervals. Analyses were stratified by osteoporotic fracture site (hip, vertebral, humerus, forearm) and evidence of elevated serum ferritin at baseline (ferritin >1000 µg/L), and sex.
resultsWe identified 20 264 eligible patients and 192 956 controls. Overall, there was a 55% increased risk of any fracture among iron overload patients (HR 1.55 [1.42-1.68]). Fracture risk was increased at all sites, with the highest risk observed for vertebral fractures (HR 1.97 [1.63-2.10]). Patients with ferritin >1000 µg/L had a 91% increased risk of any fracture (HR 1.91 [1.73-2.16]) and a 2.5-fold increased risk of vertebral fractures (HR 2.51 [2.01-3.12]). There was no increased risk among patients without elevated serum ferritin at any site. Fracture risk was similar between sexes. DISCUSSION: This large population-based cohort study found a 55% increased risk of fracture associated with iron overload. The risk was highest among patients with laboratory-confirmed iron overload, highlighting the importance for clinicians to consider initiating osteoporosis therapy in patients with serum ferritin >1000 µg/L to minimize fracture risk.
