Notes: Percentages and means are weighted. 95 % confidence intervals are listed in parentheses. Although our overall study examines U.S. adults ages 35+ years, we limit the sample to ages 55+ here to directly compare our NHIS-LMF covariate distributions to the distributions in the five cohort studies presented by Carter et al. (2015).
