Within‐subject exposure dependency in case‐crossover studies

Statistics in Medicine, 2001
AbstractIn the case‐crossover design, only cases are sampled and the hazard ratio is estimated from within‐subject comparisons of exposures at the event time and in M control periods prior to the event. We consider the effect of within‐subject dependence of exposures in successive time periods.

Differential Misclassification of Exposure in Case-Crossover Studies

Epidemiology, 2004
The aim of this study is to examine 2 types of differential misclassification of exposure in case-crossover studies. The first is the outcome-dependent misclassification of exposure, meaning that if an event has occurred, it could affect the reporting of exposure.

Semiparametric time varying coefficient model for matched case‐crossover studies

Statistics in Medicine, 2016
In matched case‐crossover studies, it is generally accepted that the covariates on which a case and associated controls are matched cannot exert a confounding effect on independent predictors included in the conditional logistic regression model. This is because any stratum effect is removed by the conditioning on the fixed number of sets of the case ...

Fluoroquinolone use and serious arrhythmias: A nationwide case-crossover study

Resuscitation, 2019
Fluoroquinolones have been associated with life-threatening ventricular arrhythmias and even sudden cardiac death. We aimed to assess the temporal relationship of fluoroquinolone use and serious arrhythmias via a case-crossover analysis of a large cohort of serious arrhythmias patients.In a national administrative database, we compare the distributions

Heat-related mortality in dairy cattle: A case crossover study

Preventive Veterinary Medicine, 2010
The relationship between mortality and stressful weather is not only a complex health, social and environmental issue, but also becomes an economical problem when considering livestock. Future-climate scenarios suggest that higher global mean temperatures could result in marked changes in the frequency of extreme temperatures.
