Short term persistence of HPV is strong predictor of subsequent CIN2+

A population based cohort study from Costa Rica has shown that women who test positive for hrHPV at enrolment and after about one year (i.e. positive/positive) have a three year cumulative incidence of CIN2+ significantly higher (17.0%, CI 12.1%-22.0%) than those who tested negative/positive (3.4%, CI 0.1%-6.8%), positive/negative (1.2%, CI 0.2%- 2.5%), and negative/negative (0.5%, CI 0.1%-0.9%).
