內容簡介:
Subgroup analysis is frequently used to uncover and confirm treatment effect heterogeneity in clinical trials. When multiple candidate subgroups are considered, we often need to make statistical inference on the subgroups simultaneously. Classical multiple testing procedures might suffer from the loss of interpretability and efficiency as they often fail to take subgroup size and subgroup effect relationship into account. In this talk, built on the selective traversed accumulation rules (STAR), we propose a data-adaptive and interactive multiple testing procedure for subgroups which can take subgroup size and subgroup effect relationship into account under tree structure. The proposed method is easy-to-implement and can lead to a more efficient and interpretable inference on tree-structured subgroups. We demonstrate the merit of our proposed method by re-analyzing the panitumumab trial with the proposed method. This talk is based on joint work with Prof. Xinzhou Guo (HKUST).
子組分析經常用于在臨床試驗中揭示和確認治療效應的異質性。當考慮多個候選子組時,我們通常需要同時對子組進行統計推斷。經典的多重檢驗程序可能會導致解釋性和效率的損失,因為它們通常未考慮子組大小和子組效應關系。在本報告中,基于選擇性遍歷累積規則(STAR),我們提出了一種數據自適應和交互式的多重檢驗程序,用于考慮樹結構下的子組大小和子組效應關系。所提出的方法易于實現,并可以實現對樹形結構子組的更高效和可解釋的推斷。我們通過使用所提出的方法重新分析泛替單抗試驗來展示我們提出的方法的優點。本報告基于與XinzhouGuo教授(香港科技大學)的合作研究。
