"A study of thousands of patients' health records found that those who were prescribed cholesterol-lowering statins had at least double the risk of developing type 2 diabetes. The detailed analysis of health records and other data from patients in a private insurance plan in the Midwest provides a real-world picture of how efforts to reduce heart disease may be contributing to another major medical concern. 'The fact that increased duration of statin use was associated with an increased risk of diabetes — something we call a dose-dependent relationship — makes us think that this is likely a causal relationship,' Zigmont [the graduate student who led the study at The Ohio State University] said."
