case-crossover and case-time-control studies: concepts, design, and analysis
background & aim: case-crossover studies are the case-control version of crossover studies. in these studies, cases and controls are the same subjects. the term crossover is applied for designs that all subjects pass through both treatment (exposure) and placebo (non-exposure) phases. in fact they are crossover of subjects between periods of exposure and non-exposure. this design ...
متن کاملApplication of case-crossover and case-time-control study designs in analyses of time-varying predictors of T-cell homeostasis failure.
PURPOSE To evaluate the association of sexual behavior and recreational drug exposures with T-cell homeostasis failure (TCHF), which corresponds to the onset of a rapid decline in an individual's T lymphocyte count, which occurs on average approximately 1.75 years prior to an initial diagnosis of acquired immunodeficiency syndrome (AIDS). METHODS A case-crossover design and a case-time-contro...
متن کاملNurse staffing level and nosocomial infections: empirical evaluation of the case-crossover and case-time-control designs.
The authors compared a case-crossover design, a case-time-control design, and a cohort design to evaluate the effect of nurse staffing level on the risk of nosocomial infections. They evaluated two strategies, conditional logistic regression and generalized estimating equation, to analyze the case-crossover study. The study was performed among critically ill patients in the medical intensive ca...

متن کاملSelection bias and confounding in case-crossover analyses of environmental time-series data.
The case-crossover study design is a popular analytic tool for estimating the effects of triggers of acute outcomes by environmental exposures. Although this approach controls for time-invariant confounders by design, it may allow for selection bias and confounding by time-varying factors. We conducted a simulation study of the sensitivity of the symmetric bidirectional case-crossover design to...
