is the ratio of risk in the treated group (EER) to the risk in the control group (CER): RR = EER/CER. RR is used in randomised trials and cohort studies.
The ratio of risk in the treated group (EER) to the risk in the control group (CER). This is used in randomized trials and cohort studies and is calculated as EER/CER. Also called relative risk. [ ] Sensitivity Proportion of people with the target disorder who have a positive test result. It is used to assist in assessing and selecting a diagnostic test/sign/symptom. See also likelihood ratio. more details...
Some investors and financial analysts try to estimate the risk an investment poses by speculating on how much the investment is likely to increase in value as opposed to how much it could decline. For example, a share priced at Rs.50 that analysts think could increase to Rs.90 or decrease to Rs.30 has a 4:2 risk ratio (the share could go up Rs.40 but down Rs.20). Critics point out that it is impossible to provide an accurate estimate of future prices, rendering risk ratios meaningless.
The comparison of the measured or estimated air concentration of a specific chemical to its health benchmark to determine either the magnitude of the risk of developing cancer or of some noncancer health effect. If the risk ratio for a chemical is less than one, the air concentration does not pose a health risk. If it greater than one, it may be of concern. The risk ratio shows just how much higher the air concentration is than the health benchmark.
A comparison of the risk of some health-related event such as disease or death in two groups.
Value obtained by dividing the probability of occurrence of a specific effect in one group by the probability of occurrence of the same effect in another group, or the value obtained by dividing the probability of occurrence of one potentially hazardous event by the probability of occurrence of another. Calculation of such ratios is used in choosing between options in risk management. RT risk management.
