The interpretation of the value of a rate ratio is similar to that of the risk ratio. Interpretation of EV/EBIT Ratio and Example. Rate ratios are closely related to risk ratios, but they are computed as the ratio of the incidence rate in an exposed group divided by the incidence rate in an unexposed (or less exposed) comparison group.
