*
Models of 30-day mortality limited to cases testing positive for Covid-19 on or before April 3, 2020 to allow 30 days of follow-up
a
Additionally adjusted for baseline comorbidity (asthma, cancer, chronic kidney disease, chronic obstructive pulmonary disease, diabetes mellitus, hypertension, liver disease, vascular
b
Modeling stations with five or more Covid-19 cases and conditioning on VA site of care
c
Low number of mortality events in age groups 20–39 (0 events) and 40–49 (3 events) thus grouped with 50–59 (23 deaths)
