统计学中的HR是危害比（Hazard Ratio）的意思，它用于描述两个或多个组在特定时间段内发生事件（如疾病、死亡等）的风险比例。危害比通常用于生存分析，特别是在医学研究中评估治疗或干预措施对患者生存时间的影响。与odds ratio（比值比）和relative risk（相对危险度）类似，hazard ratio也是一种衡量风险...
Consistent and accurate terminology would have us use hazard rate ratio with Cox regression and odds ratio with logistic regression. The term "relative risk" seems to be a default choice, regardless of the model being used. However, when relative risk is the object of the model chosen, as ...
Ratio:表示相对比,简单理解为一个数值相对于另一个数值的比值(百分比,倍数等)。它可以是同性质指标的比值,也可以是不同性质指标的比值。 备注:数值可以是绝对数,相对数,平均数等 比如下面实列: 0-14岁和15-49岁组的感染人数的相对比为 0-14岁和15-49岁组的感染率的相对比为 Rate:表示的率,在临床医学中,...
When a hazard rate ratio, obtained as the exponential of an estimated regression coefficient from the Cox model, is greater than 1.0, it consistently exceeds relative risk, and is exceeded by the odds ratio. The divergence of these distinct epidemiologic measures increases with the product of ...
Reported figures are the ratios of the incidence estimate in new cohorts to that in old cohorts. If incidence estimates remain the same across two cohorts, the ratio is 1.0. If estimates are higher in new cohorts than old cohorts, the ratio is greater than 1.0. Estimates are adjusted as fo...
Hazard ratio vs incidence rate Posted 05-19-2016 05:15 AM (5619 views) Hi, Usually when I perform Cox-regressions (PHREG - two treatment groups) the estimated hazard ratio is often quite similar to the ratio of incidence rates in each treatment groups. I now run a PHREG (2 treatment...
