Multivariate model assessing the relation of an elevated vaginal leucocyte count (WBC per ×400) in women with bacterial vaginosis to vaginal or cervical infections
| Predictor | WBC⩽5 (n = 171) | WBC>5 (n = 125) | OR (95% CI)* | p Value* |
|---|---|---|---|---|
| No (%) | No (%) | |||
| *Odds ratios, 95% confidence intervals, and p values were determined by multivariate regression controlling for age (log transformed), OCP use, vulvovaginal candidiasis, trichomoniasis, and genital chlamydia, gonorrhoea, and herpes. | ||||
| Age, median (years) (range) | 25 (14–61) | 23 (14–48) | 0.9 (0.4 to 2.3) | 0.85 |
| OCP use | 23 (14) | 24 (19) | 1.4 (0.7 to 2.8) | 0.32 |
| Vulvovaginal candidiasis | 3 (2) | 15 (12) | 7.9 (2.2 to 28.9) | 0.002 |
| Trichomoniasis | 14 (8) | 27 (22) | 3.4 (1.6 to 7.3) | 0.001 |
| Cervical chlamydia | 14 (8) | 29 (23) | 3.1 (1.4 to 6.7) | 0.004 |
| Cervical gonorrhoea | 17 (10) | 30 (24) | 2.7 (1.3 to 5.4) | 0.005 |
| Genital herpes | 6 (4) | 2 (2) | 0.7 (0.1 to 3.7) | 0.67 |
