Data on survival endpoints are usually summarised using either hazard ratio, cumulative number of events, or median survival statistics. Network meta-analysis, an extension of traditional pairwise meta-analysis, is typically based on a single statistic.
Meta-analyses of randomized controlled trialsRandomized controlled trials have been used for several years to combine data from clinical trialsClinical trials and generate estimates of treatment effect associated with a therapeutic intervention in rela
Network meta-analysis (NMA) extends the principles of conventional meta-analysis to allow assessment of multiple treatments in a single analysis. Hence it is also called as multiple treatment meta-analysis or mixed treatment comparisons. Importantly NMA can provide evidence on 'relative ranking' of ...

Network meta-analysis Randomized controlled trial 1. Introduction Hemorrhoids are a common condition in the adult population and may be found in 40% of the screening colonoscopies performed in England [1]. The most common symptoms are bleeding, pain, pruritis and mucosal prolapse [2]. The treatme...

Network meta-analysis (also known as multiple treatment comparison or mixed treatment comparison) seeks to combine information from all randomised comparisons among a set of treatments for a given medical condition. It is therefore a key tool for evidence-based medicine [24] and is currently a ver...
Alpha-blockers and antibiotics are most commonly used to treat chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) in clinical practice. Currently, increasing evidence also suggests acupuncture as an effective strategy. This network meta-analysis
进行网状Meta回归:使用适当的函数进行网状Meta回归分析,将效应值和协方差矩阵作为输入,并指定模型的相关参数,如模型类型、随机效应或固定效应模型等。 进行后续分析:根据需要,可以使用各种函数和图形来分析模型的结果,如森林图、箱线图、效应量图等。 讨论分析发表偏倚、异质性等:评估纳入研究的偏倚风险,筛选文献,并对...
