  1. aSubtotals do not add to 100% as individual participants may have had multiple pathogens and/or anatomic sites of infection
  2. bFive subjects enrolled in the control arm and eight participants in the EPT arm diagnosed with symptomatic disease subsequently tested negative for GC/CT infection by TMA
  3. cOnly cases of infection with the same organism in the same anatomic site at follow-up reported
