CI, confidence interval; HPV, human papillomavirus; PY, person-years. Incident detection infection, negative for type-specific HPV DNA at baseline followed by two consecutive detections of a specific type of HPV.
Participants at risk for HPV type (negative for type at baseline). Participants beta-globin-negative at baseline excluded from analysis.
Number of incident infections/participants negative for type-specific HPV DNA at baseline.
Number of incident infections/person-years at risk.
95% exact Poisson confidence intervals.
