  1. UA, unavailable; each asterix* indicates one patient diagnosed that particular year with S. pneumoniae endocarditis.
  2. The difference in incidence of S. pneumoniae endocarditis between age 1–20 (0/871), adults aged 21–70 (0/428) and elderly (3/395 or 0.8%) was statistically insignificant.
  3. All patient-specific blood isolates of S. pneumoniae1 (n, and as % of all patient-specific true-positive blood isolates2 (i.e. excluding contaminants).
