Investigators performed clinical validation of cases of dilated cardiomyopathy by choosing a random sample of 1,000 suspected cases in the database, and verifying the diagnosis based on clinical notes. **Idiopathic dilated cardiomyopathy. ***Total dilated cardiomyopathy (idiopathic and non-idiopathic). Please note all prevalence values are expressed per 100,000.
