  1. Values in bold = p < 0.05.
  2. *Adjusted for origin, ethnicity, age at first intercourse and number of viral types.
  3. **HR-HPV: high-risk-human papillomavirus, infection by at least one high-risk viral type from the 6 analysed here (viral load = sum of viral loads of HPV types detected/ number of HPV types detected.
  4. HPV: human papillomavirus; CIN: cervical intraepithelial neoplasia; VL: viral load; OR: odds ratio.
