The Risk Ratio = 2.7, and we could interpret this as: Those with hypertension had 2.7 times the risk of CHD compared to those without hypertension during the study period. 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. The RRR is (25% 20%) / 25% = 20%. Tip #1: If you have cumulative incidence expressed as percentage, convert % to convenient fractions so that you can express it as the excess risk in a group of people who have the risk factor. The information can help you take steps to reduce your risk. The calculator also factors in your high-sensitivity C-reactive protein (hsCRP) level. Belmont, CA: Brooks/Cole. The null value is to the measure of association when the incidence is the same in the groups being compared. WebA cardiac risk calculator is a screening tool that estimates your risk of future cardiovascular disease. However, taking greater risks tends to lead to greater rewards. If the risk were equal in the two groups the risk ratio would be 1, so we could also interpret this as an excess relative risk of 170%, i.e., the percent increase in risk compared to the baseline incidence in the reference group. For example, workshop participants were asked to self-assess their tolerance for risk at the 2016 Nebraska Women in Agriculture Conference.
