Adjusted Odds Ratios for Predictors of Human Papillomavirus (HPV) Detection
| High–Risk HPV | Any HPV | |||||
|---|---|---|---|---|---|---|
| Variable* | Reference | Levels | OR (95% CI) | P Value | OR (95% CI) | P Value |
| OR = odds ratio; CI = confidence interval; NS = not significant. *Adjusted for all other variables in this table. † Where week 1 is 0–7 days, week 2 is 8–14 days, week 3 is 15–21 days, week 4 is 22–35 days, and week 5 is 36 or more days. Week 5 includes those women with very late cycles, and women on Depo-Provera or who are menopausal. | ||||||
