^*The p values were calculated by the Mann-Whitney U test, chi-square test, or Fisher exact test, as appropriate.

^†The values are given as the number of patients, with the percentage in parentheses.

^‡The values are given as the mean and the standard deviation.

^§A risk area was defined as a hospital catchment area with >100 COVID-19 cases per 100,000 inhabitants.
