Cigarette smoking and geographic variation in coronary heart disease mortality in the United States

摘要: Abstract Striking geographic variation in death rates for coronary heart disease has been observed to occur within the United States.

The correlation noted was as high +0.76 if only most accurate consumption information were used. This could not be attributed either urbanization or softness of local water supply. It is suggested that accompanying search new hypotheses explain mortality should an attempt determine whether any established risk factors responsible.
