  1. All patients with AS were assessed using the EMRMS between Feb 7 and Oct 16, 2021.
  2. Pre-COVID-19-wave phase: 6th–17th week of 2021 (February 7–May 1, 2021).
  3. COVID-19-wave phase: 18th–29th week of 2021 (May 2–July 24, 2021).
  4. Post-COVID-19-wave phase: 30th–41st week of 2021 (July 25–October 16, 2021).
  5. * The weekly calculations are based on WHO’s year-week comparison table, where each week includes all 7 days and the first week of each year does not necessarily include January 1.
