LocalControl R软件包实现了新的方法,以解决在观察性结局研究中比较治疗或暴露时的偏倚和混淆。虽然设计和适用于涉及医学和生命科学的比较安全性和有效性研究,但该软件包可用于涉及多种混杂因素结局的其他情况。LocalControl是一个开源工具,供研究人员使用,其目的是使用观察数据生成高质量的证据。当比较观察性研究中的治疗时,该软件包实现了一系列非参数偏倚校正方法,包括生存分析设置,其中可能存在竞争风险和/或删失。该方法扩展到治疗结果差异的偏倚校正个性化预测,以及患者亚组治疗效应大小的异质性分析。
The LocalControl R package implements novel approaches to address biases and confounding when comparing treatments or exposures in observational studies of outcomes. While designed and appropriate for use in comparative safety and effectiveness research involving medicine and the life sciences, the package can be used in other situations involving outcomes with multiple confounders. LocalControl is an open-source tool for researchers whose aim is to generate high quality evidence using observational data. The package implements a family of methods for non-parametric bias correction when comparing treatments in observational studies, including survival analysis settings, where competing risks and/or censoring may be present. The approach extends to bias-corrected personalized predictions of treatment outcome differences, and analysis of heterogeneity of treatment effect-sizes across patient subgroups.
