Response to the letter commenting on ʻEffect of organised cervical cancer screening on cervical cancer mortality in Europe: a systematic reviewʼ

We thank Dr. Dugu é and colleagues for their response to our systematic review [1] on the effect of organised cervical screening on cervical cancer mortality in Europe. Dugué and colleagues emphasise how difficult it is to estimate the effect of cervical cancer screening, because no unselected unscreened group is a vailable and women who do not participate in screening often have a higher a priori risk of cervical cancer mortality. This was highlighted in their study [2], which we included in our review, that showed that self-selection bias influences estimates of cervical cancer screening effects.
