Web27 okt. 2024 · Interpretation: We are 95% confident that the relative risk of death in CHF exercisers compared to CHF non-exercisers is between 0.22 and 0.87. The null value is 1. Since the 95% confidence interval does not include the null value (RR=1), the finding is statistically significant. WebDefinition of risk ratio. A risk ratio (RR), also called relative risk, compares the risk of a health event (disease, injury, risk factor, or death) among one group with the risk among another group. It does so by dividing the risk (incidence proportion, attack rate) in group 1 by the risk (incidence proportion, attack rate) in group 2. board balance scorecard https://amdkprestige.com
