Broad definition of heart failure=numbers of patients with a registered heart failure diagnosis in any available healthcare records. Strict definition of heart failure=only patients hospitalised with heart failure as the main diagnosis.
*Countries with nationwide coverage of patients with heart failure and background populations. Background populations were estimated based on the coverage of the healthcare registries for countries in which this information was available. Random effect estimates were used to calculate pooled values and tau describes the estimated SD of the underlying data across countries.
