[R-meta] Publication bias/sensitivity analysis in multivariate meta-analysis
Hi Huang, Here are two recent studies on methods for detecting small-study effects and other forms of publication bias in multivariate meta-analysis: * Hong, C., Salanti, G., Morton, S., Riley, R., Chu, H., Kimmel, S. E., & Chen, Y. (2018). Testing small study effects in multivariate meta-analysis. *arXiv preprint arXiv:1805.09876*. https://arxiv.org/abs/1805.09876 * Rodgers, M. A., & Pustejovsky, J. E. (In Press). Evaluating Meta-Analytic Methods to Detect Selective Reporting in the Presence of Dependent Effect Sizes. Psychological Methods, forthcoming. https://doi.org/10.31222/osf.io/vqp8u James On Sun, Jun 14, 2020 at 5:54 AM Michael Dewey <lists at dewey.myzen.co.uk> wrote:

Hi all, Greetings. I have some questions about publication bias/sensitivity
analysis. First, are publication bias and sensivity analysis the same thing? If not, how are they different? Publication bias is a subset of small study effects where you know the aetiology of the small study effects. If you do not then it is safer to refer to small study effects. A sensitivity analysis could be almost anything but usually it manes fitting the model to one or more data-sets similar to the original one. Examples are leave-one-out analysis, or using only a subset of supposed higher quality studies.
Second, I saw people use funnel plot, fail-safe N, Egger?s regression
test to test publication bias ( http://www.metafor-project.org/doku.php/features), are these methods applicable to multivariate meta-analysis? Yes they are. Thanks.
Third, what do you recommend to do publication bias/sensivity analysis
in multivariate meta-analysis? Thanks
I think what analysis you do will depend on the scientific question. Michael
