Table 3 Assumed HPV distributions for each model health state for the base case and sensitivity analyses

From: Modeling the impact of the difference in cross-protection data between a human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine and a human papillomavirus (HPV)-6/11/16/18 vaccine in Canada

  1. * CP: Cross-protection – oncogenic HPV types affected by the vaccine: HPV-31,-33,-35,-39,-45,-51,-52,-56,-58,-59.
  2. † The proportion in the other HPV category was increased as required so that all cervical outcomes were associated with an HPV infection.
  3. ‡ The sum of proportions of all HPV infections were equal to more than 100% for CIN1 and CIN2/3 lesions due to multiple HPV infections. For modelling purposes, the values in each HPV category were proportionally reduced so that sum of all HPV types equals 100% .
  4. CC – Cervical cancer.
  5. CIN – Cervical Intraepithelial Neoplasia.
  6. HPV – Human papillomavirus.
