Question 5 options:

The odds ratio is a measure of the strength of the relationship between the risk factor and disease variables.

The ratio may take any positive or negative value.

An odds ratio of 5 indicates there is no increase in odds of disease among the exposed group.

An odds ratio of 0.50 indicates there is an increase in odds of disease among the exposed group.

    Incidence and prevalence rates can also be used to compare the rates of disease across different settings (places), people, or time. We therefore need measures of comparison. The ratio of two measures of disease frequency is called the relative risk. The difference between two measures of disease frequency is called the risk difference, or rate difference. In some cases, it involves a measure in an exposed group (or groups) and a measure in an unexposed or comparison group. In other...
