为解决网络Meta分析(NMA)中传递性假设(transitivity)评估方法匮乏的问题，Loukia M.Spineli团队开发了tracenma R包数据库，收录217个网络数据集，系统提取临床、人口学和方法学特征作为潜在效应修饰因子(effect modifiers)。该研究揭示了方法学特征报告最完整(99%含研究设计 ...

A general framework for studying the transitivity of reciprocal relations is presented. The key feature is the cyclic evaluation of transitivity: triangles (i.e. any three points) are visited in a ...

Arguing that the standard situation for studying transitivity prompts correct but nontransitive conclusions, we compared the standard with two other situations which were more likely to require the ...

Clustering is a common computational technique for data analysis in the life sciences. Essentially one defines clustering as a partitioning of arbitrary data objects into groups, such that the objects ...
