This discussion contribution provides some subjective early history of network meta-analysis and also proposes a new bipartite graph structure to better represent multi-arm trials. ...
Calculating the power of a planned individual participant data meta-analysis to examine prognostic factor effects for a binary outcome [0.03%]
前瞻性个体患者数据 Meta 分析的功效计算及其在二分类预后因素效应研究中的应用

Collecting data for an individual participant data meta-analysis (IPDMA) project can be time consuming and resource intensive and could still have insufficient power to answer the question of interest. Therefore, researchers should consider...
A comparison of two models for detecting inconsistency in network meta-analysis [0.03%]
一种检测网络meta分析中不一致性的方法比较研究

Lu Qin et al.
The application of network meta-analysis is becoming increasingly widespread, and for a successful implementation, it requires that the direct comparison result and the indirect comparison result should be consistent. Because of this, a pro...
Reduce, reuse, recycle: Introducing MetaPipeX, a framework for analyses of multi-lab data [0.03%]

Multi-lab projects are large scale collaborations between participating data collection sites that gather empirical evidence and (usually) analyze that evidence using meta-analyses. They are a valuable form of scientific collaboration, prod...
Performance of two large language models for data extraction in evidence synthesis [0.03%]
两种大型语言模型在证据综合中数据提取性能的比较研究
Amanda Konet,Ian Thomas,Gerald Gartlehner et al.
Amanda Konet et al.
Accurate data extraction is a key component of evidence synthesis and critical to valid results. The advent of publicly available large language models (LLMs) has generated interest in these tools for evidence synthesis and created uncertai...

Citation indices providing information on backward citation (BWC) and forward citation (FWC) links are essential for literature discovery, bibliographic analysis, and knowledge synthesis, especially when language barriers impede document id...
Bayesian pairwise meta-analysis of time-to-event outcomes in the presence of non-proportional hazards: A simulation study of flexible parametric, piecewise exponential and fractional polynomial models [0.03%]
非比例风险存在下基于贝叶斯方法的生存结局成对荟萃分析：刚性参数模型、分段指数模型和分数多项式模型的模拟研究
Suzanne C Freeman,Alex J Sutton,Nicola J Cooper et al.
Suzanne C Freeman et al.
Background: Traditionally, meta-analysis of time-to-event outcomes reports a single pooled hazard ratio assuming proportional hazards (PH). For health technology assessment evaluations, hazard ratios are frequently extrap...
The impact of continuity correction methods in Cochrane reviews with single-zero trials with rare events: A meta-epidemiological study [0.03%]
单零试验罕见事件的Cochrane系统评价中连续性矫正方法的应用效果：一项元流行病学研究

Yasushi Tsujimoto et al.
Meta-analyses examining dichotomous outcomes often include single-zero studies, where no events occur in intervention or control groups. These pose challenges, and several methods have been proposed to address them. A fixed continuity corre...
The use of fixed study main effects in arm-based network meta-analysis [0.03%]

Methods of network meta-analysis (NMA) can be classified as arm-based and contrast-based approaches. There are several arm-based approaches, and some of these have been criticized because they recover inter-study information and hence do no...
