  1. Acronyms: AIDS acquired immunodeficiency syndrome, COPD chronic obstructive pulmonary disorder, IQR interquartile range (25th percentile, 75th percentile), NAAT nucleic acid amplification test, SD standard deviation
  2. aTested patients are those that had at least one interpretable NAAT result
  3. bMeasured at time of first observed NAAT in the study period
  4. cAmerican Indian or Alaska Native” is listed as ‘N/A’, not available, for Explorys because it is not a defined race category in the system. Persons in Explorys may self-identify as multiple races. Therefore, the sum of percentages may be greater than 100%
  5. dCCI component categories are in alphabetical order. Comorbidities are measured in the period between −14 and − 379 days before the first observed SARS-CoV-2 NAAT in the study period. Persons may have multiple comorbidities. Therefore, the sum of percentages may be greater than 100%
