Timeline of study population. Simplified timeline in which each patient is a horizontal line, showing mortality and group membership by vaccination status. COVID-19 cases are shown as colored dots, with colored lines indicating survival postinfection. A per-person analysis based on the final population leads to bias, since only COVID-19 survivors are compared. But inclusion of cases circled in a per-person analysis also leads to bias, since dying from COVID-19 may be the reason for nonvaccination, whereas all the pre-vaccination cases (which are excluded) are immortal up to the time of vaccination.
