-Smoking status obtained from EHR (social history and flowsheet) within a year before SARS-COV2 testing date. For patients with multiple records, we use the last record before SARS-COV2.

-Former, current and never smokers categories were based on each patient's lifetime count of cigarettes smoked and most recent self-reported smoking status.

-Patients who self-reported as a never smoker or who had smoked less than 100 cigarettes in their lifetime were considered never smokers; patients who smoked more than 100 cigarettes in their lifetime were considered smokers (former or current) [31].

-Former smokers' status was assigned based on the patient's self-report of “former smoker” in the EHR.
