Table 3.

Age standardised mortality rates (per 100000) in Norway 2020, 2021 and 2022 by the most important cause-of-death groups, COVID-19, and missing cause of death. Predictions and 95% prediction intervals are based on trends for 2010–2019. Significant excess mortality in bold and significantly lower mortality than predicted in italics than predicted in italics
