Abstract

The win ratio is a statistical method most commonly used for analyzing composite outcomes in clinical trials. Composite outcomes comprise two or more distinct “component” events (for example, myocardial infarction or death) and are typically analyzed using time-to-first-event methods ignoring the relative importance of the component events. When using the win ratio, component events are instead placed into a hierarchy from most to least important; more important components can then be prioritized over less important outcomes (for example, death can be prioritized over myocardial infarction). Furthermore, the win ratio enables outcomes of different types (for example, time-to-event, continuous, binary, ordinal, and repeat events) to be combined. We present winratiotest, a command to implement the win-ratio approach for hierarchical outcomes in a flexible and user-friendly way.
winratiotest:在Stata中实现胜率和分层胜率的命令
胜率是一种统计方法,最常用于分析临床试验中的综合结果。复合结果包括两个或多个不同的“组成”事件(例如,心肌梗死或死亡),通常使用“到首次事件的时间”方法进行分析,忽略了组成事件的相对重要性。当使用胜率时,组件事件会按照从最重要到最不重要的顺序排列;更重要的组成部分可以优先于不太重要的结果(例如,死亡可以优先于心肌梗死)。此外,胜率允许组合不同类型的结果(例如,时间到事件、连续事件、二进制事件、顺序事件和重复事件)。我们提出了winratiotest,这是一个以灵活和用户友好的方式实现分层结果胜比方法的命令。
