Effect of intensive glucose lowering treatment on all cause mortality, cardiovascular death, and microvascular events in type 2 diabetes: meta-analysis of randomised controlled trials

The authors have alerted us to some errors in this research paper by Rémy Boussageon and colleagues (BMJ 2011;343:d4169, doi:10.1136/bmj.d4169). The end of the first sentence of the opening paragraph in the section “Policy implications” should have reflected what was said elsewhere in the paper but wrongly stated that 15-52 people would need to be treated to avoid one severe hypoglycaemic event. The full sentence should in fact read: “Overall, the absolute benefit of treatment for five years was modest—117 to 150 people would need to be treated to avoid one myocardial infarction and 32 to 142 to avoid one episode of microalbuminuria—although one severe episode of hypoglycaemia would occur for every 15 to 52 patients.” Additionally, the job titles of one of the authors, James M Wright, were partially wrong. The job titles should read clinical pharmacologist and professor of pharmacology. In the Contributors section the initials WJM should be JMW.
