Lemeshow. There were no significant differences between the two control groups with any of the risk factors considered. Body mass index was 25-55 (SD 3-59) in patients; 26-20 (3-63) in the general population controls; and 25-47 (5-15) in hospital controls. Comparing patients with each control group we found a significantly increased risk of myocardial infarction among patients who snored every night (table). Multiple logistic regression analysis showed that this association was independent of other risk factors.
