Sample size estimation for case‐crossover studies

Statistics in Medicine, 2018
Case‐crossover study designs are observational studies used to assess postmarket safety of medical products (eg, vaccines or drugs). As a case‐crossover study is self‐controlled, its advantages include better control for confounding because the design controls for any time‐invariant measured and unmeasured confounding and potentially greater ...

Triggers for Preeclampsia Onset: a Case‐Crossover Study

Paediatric and Perinatal Epidemiology, 2016
AbstractBackgroundRisk factors for preeclampsia are well established, whereas, the triggers associated with timing of preeclampsia onset are not. The aim of this study was to establish whether recent infection or other triggers were associated with timing of preeclampsia onset.MethodsWe used a case‐crossover design with preeclampsia cases serving as ...
