WebFeb 1, 2008 · A relative risk of 1.0 indicates no difference between comparison groups. In all cases, statistical significance is assumed if the 95% confidence interval (CI) around the relative risk does not include 1.0. The relative risk reduction equals the amount by which the relative risk has been reduced by treatment and is calculated as 1 – relative risk. WebThis function calculates relative risk, risk difference and population attributable risk difference with confidence intervals. You can examine the risk of an outcome, such as disease, given the incidence of the outcome in relation to an exposure, such as a suspected risk or protection factor for a disease. The study design should be prospective.
WebSignificant difference If the RR, OR, or HR = 1, or the confidence interval (CI) = 1, then there is no statistically significant difference between treatment and control groups. If the RR/OR/HR >1, and the CI does not include 1, events are significantly more likely in the treatment than the control group. WebFeb 1, 2024 · February 1, 2024 by Zach. What is Attributable Risk?
