Association between log serum titers and incident cases by HPV type.
| HPV16/31 (n = 43) | HPV16 Only (n = 26) | HPV31 ONLY (n = 17) | ||||
|---|---|---|---|---|---|---|
| OR (95% CI) § | p-Value | OR (95% CI) § | p-Value | OR (95% CI) § | p-Value | |
| Cases vs. Controls | 1.41 (1.01–1.96) | 0.0415 | 1.26 (0.82–1.92) | 0.2884 | 1.67 (0.96–2.92) | 0.0704 |
| Cases vs. Random Controls | 1.25 (0.88–1.79) | 0.2143 | 1.11 (0.69–1.77) | 0.6746 | 1.47 (0.81–2.66) | 0.2065 |
| Cases vs. HR Controls | 1.73 (1.03–2.88) | 0.0373 | 1.59 (0.80–3.14) | 0.1832 | 1.97 (0.84–4.60) | 0.1177 |
§ Odds ratio (OR) (95% confidence intervals, CI) estimated by multivariate conditional logistic regression, adjusting for the variable ‘Vaccine before coitarche’; the fitted regression models probability (relative odds) of a control having a one log unit increase in antibody titers compared to the cases; HPV, human papillomavirus; HR, high-risk.
