Card 11 / 14: The causes of lupus are poorly understood but may involve mercury. You read a study in which an investigator measured the prevalence of lupus in workers in a mercury battery factory and compared this to the prevalence of lupus in factory workers who made wind generators, a process that does not involve mercury. Lupus was present in 1% of the battery workers and none of the workers in the wind generator factor.What is the exposure (risk factor, predictor) in this study?
Answer:
The exposure of interest is mercury

The answers to questions 9 and 10 may sound obvious, but it is sometimes difficult in a medical journal article to identify the exposure and outcome of interest among all the variables examined. You should always start your analysis of a journal article by identifying the primary exposure(s) and outcome(s) of interest.
