Question: High blood pressure and cardiovascular disease. The results describing the relationship between blood pressure and cardiovascular disease are given in terms of the change in log odds in Exercise.
(a) Transform the slope to the odds ratio and the 95% confidence interval for the slope to a 95% confidence interval for the odds ratio.
(b) Write a conclusion using the odds to describe the results.
Exercise: High blood pressure and cardiovascular disease. There is much evidence that high blood pressure is associated with increased risk of death from cardiovascular disease. A major study of this association examined 3338 men with high blood pressure and 2676 men with low blood pressure. During the period of the study, 21 men in the low-blood-pressure group and 55 in the high-blood-pressure group died from cardiovascular disease.
(a) Find the proportion of men who died from cardiovascular disease in the high-blood-pressure group. Then calculate the odds.
(b) Do the same for the low-blood-pressure group.
(c) Now calculate the odds ratio with the odds for the high-blood-pressure group in the numerator. Describe the result in words.
