Erratum : Impact of coronavirus disease 2019 on patients with chronic pain: multicenter study in Korea

In the first line of results in the abstract (page 209), the percentage of ‘35.9’ is a false number. It should be the percentage of respondents who said hospital visits were reduced, but it seems to have entered the percentage of all respondents. The corrected version should be as follows: Before correction Results: A total of 914 patients completed the survey, 35.9% of whom had decreased their number of visits to the hospital, mostly due to COVID-19. After correction Results: A total of 914 patients completed the survey, 51.2% of whom had decreased their number of visits to the hospital, mostly due to COVID-19. We sincerely apologize for any confusions that we may have caused.
