Recent epidemiological studies have reported an approximately two-fold, significant, increased odds ratio for venous thromboembolism in users of third-generation oral contraceptives (OCs) compared to users of second-generation OCs. However, in each study, this association is of borderline statistical significance, and the studies do not indicate an ...

So in epidemiological studies, false inferences may be drawn that these markers (treated as risk factors) have causal or exacerbating effects on diseases which are ...
