Case-crossover design: air pollution and health outcomes.
OBJECTIVES The objective of this study was to investigate variants of case-crossover design for assessing correlations between counts of health events over time and exposure to ambient air pollution. For illustrative purposes, daily emergency department (ED) visits for depression among females were considered. MATERIALS AND METHOD Ambient nitrogen dioxide (NO(2)) was used as a principal ambie...
متن کاملCase-crossover design in air pollution epidemiology.
The case-crossover design was developed to study the effects of transient, short-term exposures on the risk of acute events, such as myocardial infarction, in the early 1990s. This paper illustrates how the principles of case-crossover design are related to the principles of crossover and case-control designs and stipulates the possibilities of case-crossover design in air pollution epidemiolog...
متن کاملCase-Crossover Analysis of Air Pollution Health Effects: A Systematic Review of Methodology and Application
BACKGROUND Case-crossover is one of the most used designs for analyzing the health-related effects of air pollution. Nevertheless, no one has reviewed its application and methodology in this context. OBJECTIVE We conducted a systematic review of case-crossover (CCO) designs used to study the relationship between air pollution and morbidity and mortality, from the standpoint of methodology and...
متن کاملOverlap bias in the case-crossover design, with application to air pollution exposures.
The case-crossover design uses cases only, and compares exposures just prior to the event times to exposures at comparable control, or 'referent' times, in order to assess the effect of short-term exposure on the risk of a rare event. It has commonly been used to study the effect of air pollution on the risk of various adverse health events. Proper selection of referents is crucial, especially ...
متن کاملBias in the Case--Crossover Design: Implications for Studies of Air Pollution
The case{crossover study design in principle allows testing for an acute health e ect of an exposure such as air pollution with restriction in time to remove seasonal confounding. We argue that much thinking about this design has been based on false analogies with matched case{control studies, and show that the usual design and analysis of case{crossover studies introduce a previously unrecogni...
