  1. The table shows disease incidence per 100,000 person-years. Rows for gender do not sum to overall number of enrollees, because those with missing information (N = 2001) were excluded from the table.
  2. ACP All-cause pneumonia; PP pneumococcal pneumonia, IPD invasive pneumococcal disease, PY person-years.
