  1. a Results are based on data weighted to reflect actual distribution of self-reported pneumonia vaccination status among all eligible study subjects in each race-ethnicity × gender group.
  2. SR = Self-report from questionnaire. HPMR = Health Plan medical record documentation of a pneumonia vaccination prior to the date of the self-report.
  3. Unwtd Ns show 2 × 2 distributions pre-weighting; Wtd N's, rounded to integer form, show the 2 × 2 distributions after post-stratification weighting.
