Causal inference study on the effect of exogenous insulin on the risk of osteoarthritis.
Article in Medicine, 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
The study explores the previously unexamined link between exogenous insulin treatment for diabetes mellitus and its potential to alter the risk of osteoarthritis (OA) using Mendelian randomization (MR) to investigate a possible causal relationship. By employing a variety of two-sample MR methodologies, including instrumental variable weighting (IVW), weighted median, MR-Egger, weighted mode, simple mode, and conducting multivariate MR (MVMR) Analysis, this research aims to assess the direct effects of exogenous insulin on OA, while also considering the mediating roles of diabetes and smoking status. Our findings through the IVW model reveal a significant causal association, indicating that exogenous insulin use is linked to a decreased risk of OA, evidenced by an odds ratio (OR) of 0.00029 (95% CI: 0-0.694, P = .040158), with no causal effect identified from OA towards exogenous insulin in reverse MR analysis. Further mediation analysis highlights diabetes and smoking as significant mediators of insulin's effect on OA, with diabetes and smoking respectively accounting for 74.26%, 70.11%, and 43.34% of the mediation effect through various indicators. Consequently, this MR study provides substantial evidence of a causal relationship between exogenous insulin use and a reduced OA risk, emphasizing the importance of holistic management for diabetic patients to carefully weigh the benefits of insulin therapy against its potential OA risks.
