Most of these methods can be similarly applied to the frequentist framework. In combination with mitochondrial reads, removing outliers from these groups. A lot of my work heavily involves time series analysis. We also show that conventional univariate Bayesian influential measures can be applied to the bivariate random effects models, which can be used as marginal influential measures. We propose four synthetic measures for influence analyses: (a) relative distance, (b) standardized residual, (c) Bayesian p-value, and (d) influence statistic on the area under the summary receiver operating characteristic curve. Synthetic influence measures based on the bivariate hierarchical Bayesian random effects models are developed because the overall influences of individual studies should be simultaneously assessed by the two outcome variables and their correlation information. In this article, we propose Bayesian methods for detecting outlying studies and their influence diagnostics in DTA meta-analyses. In addition, there might be influential studies that have notable impacts on the results. A forest plot of the meta-analysis with outliers removed can be generated directly by plugging the.

When outliers are found, the function automatically recalculates the meta-analysis results, using the same settings as in the object provided in x, but excluding the detected outliers. Studies are defined as outliers when their 95 confidence interval lies ouside the 95 confidence interval of the pooled effect. These deviating studies can be regarded as outlying with respect to the rest of the network and can be influential on the pooled results. In a network meta-analysis, some of the collected studies may deviate markedly from the others, for example having very unusual effect sizes. The inclusion of these 'outlying' studies might lead to biases, yielding misleading results. This function searches for outlying studies in a meta-analysis results object. Bayesian model-based outlier detection in network meta-analysis. We prove that evidence cycles in the treatment network play critical roles in network meta-analysis. In these DTA meta-analyses, some studies may have markedly different characteristics from the others and potentially be inappropriate to include. that make network meta-analysis outperform traditional pairwise meta-analyses. Objectives: Our aim is to propose an intuitive Bayesian model that captures deviating studies within a network of interventions and to explore the influence of such studies in the NMA results under different.

Meta-analyses of diagnostic test accuracy (DTA) studies have been gaining prominence in research in clinical epidemiology and health technology development. Whilst several outlier detection methods have been developed for standard meta-analysis, little work has been done in the field of NMA.
