  1. Note: denominators vary according to the number of samples for which each test was conducted (see Results section).
  2. 1 Nugent's categories: score 0–6 = normal and intermediate flora; score 7–10 = BV.
  3. 2 From Fisher's Exact test.
  4. 3 Includes Bacteroides spp., Prevotella spp. and Peptostreptococcus spp. isolates and other anaerobes.
  5. 4 Anaerobic isolates were found in 21 samples out of 66; 5 women had more than 1 anaerobic isolate in which case the highest level of growth was used for the significance test.
  6. 5 Anaerobic Gram-negative rods, anaerobic Gram-positive or pigmented anaerobes.
