#Comprehensive meta analysis outliers software
I am sure I will use this software for upcoming meta-analyses in the future. Using the four proposed methods, we could detect three potential influential trials involving an obvious outlier that was retracted because of data falsifications. Meta-analysis becomes very easy with the help of Comprehensive Meta-Analysis. We illustrate the effectiveness of the proposed methods via applications to a network meta-analysis of antihypertensive drugs. The authors conducted a meta-analysis to integrate research on the effects of IPT. Numerous practice guidelines have recommended IPT as a treatment of choice for unipolar depressive disorders. We also propose (4) a model-based approach using a likelihood ratio statistic by a mean-shifted outlier detection model. Interpersonal psychotherapy (IPT), a structured and time-limited therapy, has been studied in many controlled trials.
We propose three influential measures by a leave-one-trial-out cross-validation scheme: (1) comparison-specific studentized residual, (2) relative change measure for covariance matrix of the comparative effectiveness parameters, (3) relative change measure for heterogeneity covariance matrix. In particular, we propose suitable influence measures for network meta-analysis models that involve missing outcomes and adjust the degree of freedoms appropriately. In this article, we propose effective methods for detecting outlying and influential studies in a frequentist framework. The inclusion of these "outlying" studies might lead to biases, yielding misleading results. outliers excluded refer to computing analyses with and without outliers. study of lower quality or one that appears to be an outlier are examples of the reasons for removing a study in a sensitivity analysis. (1987) integrated many meta-analyses to assess the model of school learning. with an emphasis on intuitive outlier detection and exploratory data analysis. Meta-analysis is a statistical method for pooling the results of several studies reporting the. The first edition of this book in 1978 brought the first comprehensive text on outlier methods in statistical analysis. possible publication bias, outliers, or other patterns of notable effects. In many network meta-analyses, some of the constituent studies may have markedly different characteristics from the others, and may be influential enough to change the overall results. Additionally, you will be able to create a comprehensive analytical report. On the contrary, a thorough meta-analysis catalogs the major substantive and.

Network meta-analysis has been gaining prominence as an evidence synthesis method that enables the comprehensive synthesis and simultaneous comparison of multiple treatments. Meta-DiSc is a free software to perform Meta-analysis of studies of evaluations of Diagnostic and Screening tests.
