Risk ratio and hazard ratio

WebThe relative risk is different from the odds ratio, although the odds ratio asymptotically approaches the relative risk for small probabilities of outcomes.If IE is substantially smaller than IN, then IE/(IE + IN) IE/IN. Similarly, if CE is much smaller than CN, then CE/(CN + CE) CE/CN. Thus, under the rare disease assumption = (+) (+) =. In practice the odds ratio is … WebThe hazards of hazards ratios [commentary].
