Note: CI = confidence interval, ICU = intensive care unit, LTC = long-term care.
We observed cases from the index date until death or censoring. Controls were censored on the date of death or censoring of their matched person with COVID-19. Costs in each 30-day period include only people with COVID-19 and controls who were under observation at the start of the period.
