DESIGN AND SETTING: Expected detection rates of invasive cancers at prevalent screen are calculated, using estimates of the underlying England and Wales incidence rates and age specific prevalence incidence ratios from the Swedish Two County Study. Expected interval cancer rates are also derived from ...
Results The procedure is exemplified by examining of the relation between panic attack and the subsequent incidence of MDD. Conclusions The results reveal that the adjustment for all other variables, irrespective of their temporal relation to X , can yield a false negative result (despite ...

The strong correlation between EMIS derived self-reported HIV diagnosis incidence and surveillance system derived data critically depends on an estimated parameter, the size of the respective MSM populations. The SSD, calculated to assess whether similar parts of the MSM population were reached by the...
