There is more, but you're probably busy being sick into a bin – the one I got for my flat ages ago, before everyone had them.
We included in our sensitivity analyses an alternative calibration of age-specific susceptibilities that gave rise to a flat age-specific attack rate, similar to that of the 1968 pandemic [21] (see Supporting Information Text S2).
Melanoma have a flat age-incidence curve, whereas for other skin cancers, the increase is exponential with age.
Therefore, a flat age-curve suggests that in certain populations in developing countries, young women do not acquire new HPV infection more frequently than older women.
The young age structure of populations in developing countries coupled with a rather flat age-incidence curve (Fig. 3) implies that the mean age at diagnosis in developing countries is lower than that of European and American populations.
There was no evidence of higher prevalence in younger women, confirming the flat age-specific curve seen in other low-resource countries in Asia and Africa (Franceschi et al, 2006), although at much lower HPV prevalence.
Consideration of the very flat age-dependent trajectories of these parameters in controls in our earlier reports shows that this effect is much greater in opioid dependence than might be expected on the basis of the higher CA in the opioid-dependent group alone.
