  1. *n (% of non-missing). 1mean number of daily symptoms were computed for period spanning 3 days before to 3 days after the diagnosis date (for participants with a confirmed diagnosis). In the overall sample, n = 61,063 had available age data; n = 61,062 had available sex data, education data, and frontline worker status data; n = 61,017 had available race data; n = 61,061 had available ethnicity data; and n = 61,015 had available comorbid condition data. Within COVID-19 training data, n = 72 had available data for age, sex, race, ethnicity, education, frontline worker status, and comorbid conditions; n = 69 had available data for symptoms. Within COVID-19 independent validation data n = 8 had available data for symptoms; n = 10 had available data for all other characteristics.
