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
