HPV16 serology results by incident HPV16 DNA infection status for the 388 subjects selected for assay measurement.

ELISA: VLP-based direct enzyme-linked immunosorbent assay; cLIA: Competitive Luminex immunoassay; SEAP-NA: Secreted alkaline phosphatase protein neutralization assay.Values less than the level of quantification are shown as “aSampling-adjusted population estimates for the original cohort estimated using Inverse-probability weights (see methods). For calculation of sampling-adjusted values, the assay values under the level of quantification were assumed to be midway in the range. For example, ELISA values
