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 … 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. ttthota
