WebAs a shape, it is very nice looking to tell that the hazard is decreasing over time, but the hazard value on the Y-axis ranged between 0.00015 to 0, I don’t know how to interpret it. WebHowever, as the assumption of both the Cox model and log-rank test are that the hazard ratio stay constant over time, so I think I can also calculate the HR and 95% CI using the log-rank test. According to the book Survival Analysis: A Practical Approach, I got two formulas on Page 62 and 66 to do this (as shown below).
ハザード比（はざーどひ、英: hazard ratio、HR）は生存分析では、2つのレベルの説明変数によって記述された条件に対応するハザード率の比である。たとえば、医薬品の研究においては、治療群の単位時間当たりの死亡率は、対照群の死亡率の2倍になる可能性がある。このときハザード比は2となり、治療による死亡のハザード（危険）が高いことを示す。ハザード比が相対リスクやオッズ比と異なるのは、相対リスクやオッズ比が定義されたエンドポイント（疾患の … WebIn this tutorial, I’m going to show you how to create a forest plot by using Microsoft Excel.
