• Island jurisdictions were analysed separately because their pandemic experience differed materially from non-island jurisdictions. — Global Health Security Index and COVID-19 pandemic mortality 2020–2021: a comparative study of islands and non-islands across 194 jurisdictions
• Islands had much lower mean age-standardised excess mortality than non-islands during 2020-2021. — Global Health Security Index and COVID-19 pandemic mortality 2020–2021: a comparative study of islands and non-islands across 194 jurisdictions
• Many islands used geography to support border closure, exclusion, or elimination strategies during the pandemic. — Global Health Security Index and COVID-19 pandemic mortality 2020–2021: a comparative study of islands and non-islands across 194 jurisdictions
• The GHS Index did not meaningfully predict mortality outcomes among island jurisdictions. — Global Health Security Index and COVID-19 pandemic mortality 2020–2021: a comparative study of islands and non-islands across 194 jurisdictions
• Many island jurisdictions achieved strong mortality outcomes despite relatively low GHS Index scores, weakening the global association between GHS scores and pandemic mortality. — Global Health Security Index and COVID-19 pandemic mortality 2020–2021: a comparative study of islands and non-islands across 194 jurisdictions
• Missing data limited island-specific analyses and may have excluded islands with strong COVID-19 outcomes. — Global Health Security Index and COVID-19 pandemic mortality 2020–2021: a comparative study of islands and non-islands across 194 jurisdictions
