^aResults from multiple regression analysis. Inclusion of the variables smoking, logAHI, myocardial infarction, sleepiness, use of antidepressants, and use of hypnosedatives in the model did not affect the relationship between any covariate on the dependent variables

^b β is the unstandardized regression coefficient of the variable

^cSE is the standard error of β

^dUnit of age, 5 years
