c**********e 发帖数: 2007 | 1 If the two ratios are from two group of subjects,
it would be easy.
Now the two ratios are from the same group of subjects.
One before treatment (only one treatment), and one
after treatment. For example, before treatment,
55% (55 out of 100) of patients have high blood pressure.
After treatment, 50% (50 out of 100) have high blood
pressure. Are the two ratios significant?
Thanks a lot! |
