Network meta-analysis can make multiple indirect comparisons, thus allowing to assess a range of treatment options against a commonĬomparator. MetaXL now offers anĪlternative, the Doi plot, which is much easier to interpret. Traditionally, the funnel plot is used to detect possible publication bias, but this plot is often hard to interpret. To get published than ones with ‘negative’ results. Publication bias can occur, among other reasons, because studies with ‘positive’ results are more likely Much of the heterogeneity between study results is explained by differences in study quality, and it is preferable to make use of this information explicitly. Pooled estimate when studies exhibit heterogeneity (without inappropriate changes to individual study weights, as the random effects model does), thus keeping the MSE lower than with the random effectsĢ) The QE model allows incorporating information on study quality into the analysis, thereby affording the opportunity for further reduction in estimator MSE beyond that of the IVhet model. MetaXL offers two alternatives to the RE model:ġ) The IVhet model provides a quasi-likelihood based expansion of the confidence interval around the inverse variance weighted For these reasons it is seriously flawed and It also makes unjustifiable changes to study weights. Statistical error and has a larger mean squared error (MSE) than even the fixed effects estimator. However the RE estimator, as explained in the MetaXL User Guide, underestimates the
Heterogeneity is usually dealt withīy employing the random effects (RE) model. There are two main issues with meta-analysis: heterogeneity between studies, and publication bias. It produces a weighted average of the included studies results. Meta-analysis is a statistical method to combine the results of epidemiological studies in order to increase power. Now version 5Īdds cumulative meta-analysis to this already rich list of features
Version 2 the inverse variance heterogeneity (IVhet) model, version 3 introduced the Doi plot and LFK index for the detection of publication bias, version 4 added network meta-analysis. Version 1 introduced the quality effects (QE) model, Here I choose By word and 10 as an example.MetaXL keeps pushing the envelope of innovation in meta-analysis. Then Fly In dialog box will display, adjust the option of animation text and the value of delay percentage in Enhancements group. Go back to Animations tab, click Animation Pane and click drop-down button in the right pane, then select Effect Options.ĥ. Method 2: Animate Text by Letter, Word or ParagraphĤ. The final effect will display automatically. Choose preferred type in the drop-down list, here I pick Fly In as an example.Ĥ. Click Add Animation in the Advanced Animation group.ģ. Select the whole text and go to Animations tab.Ģ. Here’s a simple guide to you for reference: Method 1: Animate Text by Paragraphġ. Besides, it is also possible to add animation to text by letter, word or paragraph, and you can even set the delay percentage of it. If there is a lot of text in the document, animating text could lead to different visual experience and help make the message clearer to the audience. When making a PowerPoint presentation, you might animate pictures frequently.
