CI, confidence interval; SE, standard error.

Age was centered around the mean of 86.91 years. Sex was coded as 0 (women) and 1 (men). Month was coded as 0 (December), 1 (January), 2 (February), and 4 (April). NH restrictions were coded as 0 (December/January/February) or 1 (April). Test statistics for fixed effects and variance components were t-tests and Wald z, respectively.

NH restrictions are the time periods where nursing home restrictions were implemented.
