|---|---|---|---|---|---|
| SV | FV1 | FV2 | PRb | Log concnc | |
| Total women (n = 22) | 95/2.3 ± 1.5 | 50/2.4 ± 1.4 | na | * | |
| Women in remission at FV1 (n = 11) | 10/2.3 ± 1.3 | 1/−0.02 ± −0.9 | 4/1.8 ± 0.5 | * | **; # |
| Women in remission at FV2 (n = 6) | 83/2.4 ± 1.4 | 0/ns | 0/ns | * | *; # |
a
Concentration data are expressed as log ng of G. vaginalis DNA per μg of total DNA extracted from the vaginal sample. PR, prevalence rate; na, not available; ns, no signal registered from qPCR analysis.
b
Chi-square analysis of contingency was used to test differences in the prevalence rates. *, P < 0.005.
c
Wilcoxon's signed-rank test was used to test differences in the log IF values of each bacterial group. *, P < 0.05 for FV1 versus SV; **, P < 0.005 for FV1 versus SV; #, P < 0.05 for FV2 versus SV.
