Background: Characterization studies of COVID-19 patients with Open Peer Review Approval Status
Data availability Underlying data Raw data from each database cannot be shared due to data privacy and governance requirements but raw data could be accessed according to the terms and conditions of each data source. The data source information including the terms and conditions for data access can be found in Table 8 . Analyses were performed locally in compliance with all applicable data privacy laws. All aggregate data has been made freely available for public inquiry (https://data.ohdsi.org/Covid19Charac-terizationCharybdis/). All analytic code and result sets have been made available (https://github.com/ohdsi-studies/Covid19Characterization-Charybdis). Archived analysis code as at time of publication: https://doi. org/10.5281/zenodo.5779264 28
David Moreno Martos We sincerely thank Dr. Tomlinson for reviewing the manuscript. 1. I think the definition of hospital cases will include those who caught COVID-19 while in hospital. These people tended to have a different disease course and may not represent the patients who were admitted with COVID-19. This could be pointed out as a limitation.
RESPONSE: The hospitalized cohort were defined as patients with a hospitalization episode and a clinical diagnosis of COVID- 2. There is likely to be some misclassification of asthmatics who were classified through medication use and were asthma had not been coded. These people may have fewer comorbidities than those with COPD: again this is simply a minor limitation.

'abstract': '<ns3:p><ns3:bold>Background</ns3:bold>: Characterization studies of COVID-19 patients with '
'chronic obstructive pulmonary disease (COPD) are limited in size and scope. The aim of the '
'study is to provide a large-scale characterization of COVID-19 patients with '
'COPD.</ns3:p><ns3:p> <ns3:bold>Methods</ns3:bold>: We included thirteen databases '
'contributing data from January-June 2020 from North America (US), Europe and Asia. We defined '
'two cohorts of patients with COVID-19 namely a ‘diagnosed’ and ‘hospitalized’ cohort. We '
'followed patients from COVID-19 index date to 30 days or death. We performed descriptive '
'analysis and reported the frequency of characteristics and outcomes among COPD patients with '
'COVID-19.</ns3:p><ns3:p> <ns3:bold>Results</ns3:bold>: The study included 934,778 patients in '
'the diagnosed COVID-19 cohort and 177,201 in the hospitalized COVID-19 cohort. Observed COPD '
'prevalence in the diagnosed cohort ranged from 3.8% (95%CI 3.5-4.1%) in French data to 22.7% '
'(95%CI 22.4-23.0) in US data, and from 1.9% (95%CI 1.6-2.2) in South Korean to 44.0% (95%CI '
'43.1-45.0) in US data, in the hospitalized cohorts. COPD patients in the hospitalized cohort '
'had greater comorbidity than those in the diagnosed cohort, including hypertension, heart '
'disease, diabetes and obesity. Mortality was higher in COPD patients in the hospitalized '
'cohort and ranged from 7.6% (95%CI 6.9-8.4) to 32.2% (95%CI 28.0-36.7) across databases. '
'ARDS, acute renal failure, cardiac arrhythmia and sepsis were the most common outcomes among '
'hospitalized COPD patients. \xa0</ns3:p><ns3:p> <ns3:bold>Conclusion</ns3:bold>: COPD '
'patients with COVID-19 have high levels of COVID-19-associated comorbidities and poor '
'COVID-19 outcomes. Further research is required to identify patients with COPD at high risk '
'of worse outcomes.</ns3:p>',
