研究人员开发了一种名为对比空间投影（contrast-space projection）的网络荟萃分析（NMA）新方法。该技术在NMA中提供了直接和间接证据贡献的精确不变分解。该框架允许对证据进行可重复和可解释的分析，并提供新颖的可视化工具，如可以重建NMA估计量的森林图。 AI

排序理由这是一篇在arXiv上发表的关于新统计学方法的学术论文。

Contrast-Space Projection for Network Meta-Analysis: An Exact and Invariant Study-Based Decomposition of Direct and Indirect Contributions

arXiv:2604.21994v1 Announce Type: cross Abstract: Network meta-analysis (NMA) combines direct and indirect comparisons across a connected treatment network to estimate relative treatment effects. However, there is a lack of exact contribution decompositions that reproduce NMA est…

Contrast-Space Projection for Network Meta-Analysis: An Exact and Invariant Study-Based Decomposition of Direct and Indirect Contributions

Network meta-analysis (NMA) combines direct and indirect comparisons across a connected treatment network to estimate relative treatment effects. However, there is a lack of exact contribution decompositions that reproduce NMA estimates, particularly in the presence of multi-arm …
