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). WebYou can select any level of significance you require for the confidence intervals. The odds ratio calculator will output: odds ratio, two-sided confidence interval, left-sided and right-sided confidence interval, one-sided p-value and z-score. If the test was two-sided, you need to multiply the p-value by 2 to get the two-sided p-value.

WebJun 7, 2007 · Background. In systematic reviews and meta-analyses, time-to-event outcomes are most appropriately analysed using hazard ratios (HRs). In the absence of individual patient data (IPD), methods are available to obtain HRs and/or associated statistics by carefully manipulating published or other summary data. 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 …
