aRelative risk by age group is adjusted for race and ethnicity and the number of underlying medical conditions (chronic kidney disease, chronic obstructive pulmonary disease, coronary artery disease, heart failure, hypertension, diabetes, and obesity); relative risk by race and ethnicity is adjusted for age and underlying medical conditions.
bN/A: not applicable.
cDue to the small number of cases in the younger age groups, only veterans aged ≥50 years were included in these models.
dVeterans aged 50-64 years were the reference group for veterans aged 65-74 years, 75-84 years, and ≥85 years.
eFor the models comparing veterans aged <65 years with ≥65 years, all cases and age groups were included (≥18 years) and combined into the 2 age groups (ie, 18-64 and ≥65 years old). Veterans aged 18-64 years old served as the reference group.
