摘要:

随机对照试验(RCT)被认为是检验临床领域因果假设的金标准。然而,在一个假设的因果关系的途径,病人的预后变量的调查是不可行的,使用标准的统计方法。在这里,我们提出了一种新的自动因果推断方法(AutoCI)建立在不变的因果预测(ICP)框架的因果重新解释的临床试验数据。与现有的方法相比,我们表明,拟议的AutoCI允许有效地确定因果变量,在两个真实世界的子宫内膜癌患者的RCT中具有明确的分化,具有成熟的结局和广泛的临床病理学和分子数据。这是通过大幅抑制非因果变量的因果概率来实现的。在消融研究中,我们进一步证明了AutoCI对因果概率的分配在存在混杂因素的情况下保持一致。总之,这些结果证实了AutoCI在现实世界临床分析中未来应用的稳健性和可行性。

英文摘要:

Randomized controlled trials (RCTs) are considered as the gold standard for testing causal hypotheses in the clinical domain. However, the investigation of prognostic variables of patient outcome in a hypothesized cause-effect route is not feasible using standard statistical methods. Here, we propose a new automated causal inference method (AutoCI) built upon the invariant causal prediction (ICP) framework for the causal re-interpretation of clinical trial data. Compared to existing methods, we show that the proposed AutoCI allows to efficiently determine the causal variables with a clear differentiation on two real-world RCTs of endometrial cancer patients with mature outcome and extensive clinicopathological and molecular data. This is achieved via suppressing the causal probability of non-causal variables by a wide margin. In ablation studies, we further demonstrate that the assignment of causal probabilities by AutoCI remain consistent in the presence of confounders. In conclusion, these results confirm the robustness and feasibility of AutoCI for future applications in real-world clinical analysis.
