Number of deaths in individuals aged 15–64 years during 2004–2018. Age-specific mortality rates in the Finnish general population were used in calculating expected deaths for bipolar disorder. Excess deaths proportion is calculated as the number of excess deaths/observed deaths. Causes of death are defined according to the International Classification of Diseases, 10th revision.
