Document Summary

If small, clinically significant differences may not reach statistical significance. If large, clinically insignificant results may be found to be statistically significant. ** exam: test knowledge on difference between these two concepts.

Relates to the frequency and the patterns occurrence in a population: frequency: prevalence or how often the disease occurs. In 1996 the prevalence of all cvd in the us was estimated to be. It is virtually the only way in which a quantitative understanding of the exposure- disease/health risk relationship can be obtained: exposure: the (cid:272)o(cid:374)ditio(cid:374)/(cid:271)eha(cid:448)iour that (cid:449)e e(cid:374)gage i(cid:374) or do(cid:374)"t e(cid:374)gage i(cid:374, disease: the result of the exposure. It would be unethical to randomize a group of individuals to either drinking or non-drinking condition, wait 10 years the see how much death and disease, drinking causes.
