How many women have HPV?

Through the biostats information gleaned from the “ARTISTIC” trial and the U.K.’s NHS data, in addition to the wonderfully powerful tool of Bayesian Calculation, here’s a cool chart showing the estimated prevalence of HPV by age for women.  It uses an elegant model to extract likelihoods based on known probabilities.

You can easily see why patients between the ages of 21-24 are treated differently than at older ages (by the ASCCP guidelines) for pap smears of ASC-US and LSIL.  (Interpretation: the bump is biggest in the teenage years to the mid 20s.  Any guesses why?)
