  1. Acronyms: IQR interquartile range (25th percentile, 75th percentile), NAAT nucleic acid amplification test, SD standard deviation
  2. aHospitalization rate is estimated among patients with a positive NAAT who were hospitalized within ±14 days of a positive NAAT result
  3. bMeasured at time of first observed NAAT in the study period
  4. c“American Indian or Alaska Native” is listed as ‘N/A’, not available, for Explorys because it is not a defined race category in the system. Patients in Explorys may self-identify as multiple races. Therefore, the sum of percentages may be greater than 100%
