Kaplan Meyer survival curves representing treatment failure in relation to the type of treatment (ablative in red/local in green or excisional treatment in blue) in the total combined population of HIV-positive and negative women. Crosses represent normal follow-up smears (censored  =  no treatment failure) while decreases of the curve represent a treatment failure. The risk of treatment failure is higher when an ablative or local therapy is used compared to an excisional procedure (log-rank test  <  0.001)
