Notes: CMV = cytomegalovirus; HH = household; HRS = Health and Retirement Study; HS = high school; IPR = income to poverty ratio. Weighted means and standard errors are reported for continuous variables. Weighted frequency distributions are reported for categorical variables. Higher CMV tertile indicates higher CMV IgG antibody response.
