  • Note: Categorical measures are reported as frequency (percent). Continuous measures are summarized as mean (SD).

  • a For example, chronic lung disease, renal disease, chronic hypertension, diabetes, or active cancer.

  • b High risk defined as age ≥60 years or any “Yes” response to any of the 4 diagnoses and/or conditions (heart disease, diabetes, lung disease, or immunocompromised). To be classified as high risk, the union of any of these definition components could be missing responses as long as at least one of the specified criteria were met. Low risk defined as age <60 years and responded “No” to all 4 diagnoses and conditions (heart disease, diabetes, lung disease, and immunocompromised). To be classified as low risk, all definition components must be nonmissing with all responses meeting the intersection of all low-risk criteria.
