  1. Note: For each comorbidity, the reference group is the patients who do not have the respective comorbidity
  2. IRR incidence rate ratio, CL confidence limit
  3. aAny of the above comorbidities means if patients have any of the either comorbidities mentioned above
  4. Data for outpatient visits, hospitalization visits and emergency room visits for each of the comorbidities for the controlled variables are not reported here, but these can be made available upon request
