Natural History of Progression of HPV Infection to Cervical Lesion or Clearance: Analysis of the Control Arm of the Large, Randomised PATRICIA Study
Figure 4
Summary according to HPV type of prevalence in 6MPI, risk of progression to CIN3+ lesion and chance of clearance.
Dark-shaded boxes: high prevalence (>10%), high risk of progression (HR >20) or low chance of clearance (HR <0.85)
Medium-shaded boxes: medium prevalence (5–10%), medium risk of progression (HR 5–20) or medium chance of clearance (0.85-<0.95)
Light-shaded boxes: low prevalence (<5%), low risk of progression (HR <5) or high chance of clearance (HR ≥0.95)
Definitions of high, medium and low prevalence, risk of progression and chance of clearance are arbitrary and are based on the results of the present study.
6MPI: 6-month persistent infection; CIN: cervical intraepithelial neoplasia; HPV: human papillomavirus; HR: hazard ratio.
