Ratio（比）：是两个变量的数值之商，表示分子和分母之间的数量关系。流行病学指标 比值比（OddsRatio）：某事物发生的可能性与不发生的 可能性之比。因此比值比OR 病例组的暴露比值a/c对照组的暴露比值b/d adbc 相对危险度（RR）：RR表明暴露组发病或死亡的危险是非 暴露组的多少倍。

Odds Ratio Interpretation; What do the Results mean? An odds ratio of exactly 1 means that exposure to property A does not affect the odds of property B. An odds ratio of more than 1 means that there is a higher odds of property B happening with exposure to property A. ...
