1Prevalence estimates are standardized according to the age and sex distribution in the Dutch population in 2008.

2 The odds ratio represents the ‘probability’ for co-occurrence of 2 chronic diseases. Two chronic diseases co-occur more frequent than would be expected on basis of independency if the odds ratio is larger than 1.0 and the 95% confidence interval does not include 1.0.

3 The prevalence of comorbidity of diabetes mellitus and coronary heart disease is 3.6%. Diabetes mellitus and coronary heart disease co-occur significantly more frequent than expected on basis of independency, with an odds ratio of 1.9.

* Co-occurrence of diseases occurred more frequent than expected on basis of independency (p < 0.05).
