Assignment task:
Among workers in a fish processing plant, 30% of all deaths were due to myocardial infarction (heart attack). Among workers in a brewery, 10% of all deaths were due to myocardial infarction. Investigators concluded that working in the fish processing plant caused a greater risk of death due to myocardial infarction than working in the brewery. This conclusion: Is correct because 30% > 10% May be incorrect because it is based on proportionate mortality May be incorrect because it is based on case fatality for myocardial infarction in both work sites Maybe incorrect because consumed fish oil is protective against death due to myocardial infarction.
