Comparison of cardiovascular risk between patients with type 2 diabetes and those who had had a myocardial infarction: cross sectional and cohort studies

An editorial error occurred in the abstract of this paper by Josie M M Evans and colleagues (20 April, pp 939-42). In the results section the risk ratios for the cross sectional study were the wrong way round. The adjusted risk ratio for death from all causes for patients who had had myocardial infarction compared with those with diabetes should have been 1.33 (95% confidence interval 1.14 to 1.55) [not 2.27 (1.82 to 2.83)], and the risk ratio for hospital admission for myocardial infarction should have been 2.27 (1.82 to 2.83) [not 1.33 (1.14 to 1.55)].
