Abbreviations: aPR = adjusted prevalence ratio; CI = confidence interval; 4vHPV = quadrivalent HPV vaccine; 9vHPV = 9-valent HPV vaccine; PR = prevalence ratio.
* All analyses were weighted using the National Health and Nutrition Examination Survey examination sample weights.
† Adjustments for aPR: females aged 14–19 years, race/ethnicity and ever had sex; females aged 20–24, 25–29, and 30–34 years, race/ethnicity and number of lifetime sex partners (fewer than three or three or more).
§ HPV 6, 11, 16, or 18.
¶ Relative standard error >30% and ≤50%, considered unstable.
** HPV 31, 33, 45, 52, or 58.
†† Thirty-three HPV types detected using linear array that are not HPV 6, 11, 16, or 18.
§§ Twenty-eight HPV types detected using linear array that are not HPV 6, 11, 16, 18, 31, 33, 45, 52, or 58.
