Table 2.
Basic characteristics of countries stratified by how many waves of COVID-19 they have experienced. The ‘Count’ variable indicates the number of countries in the cohort; not all characteristics are available for all countries in the cohort. The time T0 is the date of the tenth cumulative death.
| Countries with 1 wave |
