Association of habitual glucosamine use with risk of microvascular complications among individuals with type 2 diabetes: a prospective cohort study in UK biobank.
Article in Nutrition & diabetes, 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
backgroundGlucosamine is a widely used supplement for treating osteoarthritis and joint pain. New evidence suggests a potential association between glucosamine and type 2 diabetes, inflammation and cardiometabolic risk. We aimed to prospectively evaluate the association of habitual glucosamine use with risk of diabetic microvascular complications based on data from the large-scale nationwide prospective UK Biobank cohort study.
methodsThis analysis included 21,171 participants with type 2 diabetes who were free of microvascular complications from the UK Biobank. Incidence of diabetic microvascular complications was ascertained via electronic health records. The Cox proportional hazards model was used to assess the relationship between glucosamine use and the risk of diabetic microvascular complications. Subgroup analyses and sensitivity analyses were performed to explore the potential effect modifications and the robustness of the main findings.
resultsAt baseline, 14.5% of the participants reported habitual use of glucosamine supplements. During a median follow-up of 12.3 years, 4399 people developed diabetic microvascular complications, including 2084 cases of incident diabetic nephropathy, 2401 incident diabetic retinopathy, and 831 incident diabetic neuropathy. Glucosamine use was significantly associated with lower risks of composite microvascular complications (hazard ratio (HR) 0.89, 95% CI: 0.81 to 0.97) and diabetic nephropathy (HR 0.87, 95% CI: 0.76 to 0.98) in fully adjusted models. However, there was no significant inverse association between glucosamine use and the risk of diabetic retinopathy (HR 0.94, 95% CI: 0.83 to 1.06) or diabetic neuropathy (HR 0.88, 95% CI: 0.71 to 1.08).
conclusionsHabitual use of glucosamine supplement was significantly associated with lower risks of composite microvascular complications and diabetic nephropathy but not retinopathy or neuropathy in individuals with type 2 diabetes.
