"EU15+ countries were chosen as the cohort for comparison for two main reasons: firstly, this group of countries has been used previously in comparative observational analyses because of their similarly high health expenditure. Secondly, the data available for each of the EU15+ countries is of high quality. Indeed, the GBD study authors assess the quality of data available for all countries worldwide, based on the accessibility and completeness of vital registration (VR) and verbal autopsy (VA) data: all EU15+ countries have >/= 90% completeness of VR and VA data for every year from 1990 to 2019."
