Hello fellow meta-analysis colleagues, I have recently started using metafor and am still exploring. Currently, I am working on a mini meta-analysis of three studies I ran myself. In recent psychology journal I have seen the use of...

Hello all, I am trying to run a meta-analysis with specified weights, but even though the code seems right the analysis seems to apply the default weights rather than the ones I specify - is there something wrong with the...

Hello metafor users, I am currently making a forest plot for a meta-analysis, I am using forest.default and am using vectors with the effect size, low CI, high CI as input. I have been wondering whether there is...

Hello metafor community, I have one last question on forest plots - I am trying to add labels to the forest plot ("Study", "Weights", "Cohen's d [95%]"). From the metafor instruction I understand I do this via the ilab, ilab...

Dear Metafor Community, I hope this email finds you well. I have a question regarding the metafor package. I made a forest plot using the code below. I have received feedback that, as the forest plot shows odds ratios I...

Hello Wolfgang, thank you very much for your advice and your reading suggestions (will take me a while to catch up on those...) - based on your instructions I am using this code now to run the (mini) meta-analysis. slope...

Aw, great, that is very useful, thanks a lot! All the best, Antonia On 6 August 2018 at 14:38, Viechtbauer, Wolfgang (SP) < wolfgang.viechtbauer at maastrichtuniversity.nl> wrote: > The weights are only rescalled to percentages when using weights(). > Internally...

Hello James, thank you very much for your reply, that was very useful - I hadn't realised the numbers were re-scaled versions of the ones I had specified! If I understand this correctly then, the re-scaling does not...

Hello Wolfgang, yes, I noticed that this is a difficult one... Yes, the studies are (almost) equivalent, using the same DV's and IV's. Would you then recommend meta-analyzing the standardized or non-standardized regression coefficients? Thank you...

Hello Wolfgang, thank you very much for your reply. It seems like eta squared might not be the most straightforward option then when intending to work with metafor. Would you recommend another effect size for an interaction effect from a...

Thank you - now it loos right! :) Just to double check - if I wanted to run the analysis with a random effects model, rather than a fixed effects model, would I just delete the "method="FE""? This is what I understand...

Thanks a lot, Wolfgang! That makes sense, but we have a lot more studies in our meta-analysis and used the random effects model. All the best, Antonia On Wed, 11 Mar 2020 at 11:06, Viechtbauer, Wolfgang (SP) < wolfgang...

Hello Wolfgang and Michael, great, thank you so much for your help, it worked! :) All the best, Antonia On Mon, 27 Aug 2018 at 13:53, Michael Dewey <lists at dewey.myzen.co.uk> wrote: > Dear Antonia > > You need to...

Hello Wolfgang, thank you, and apologies - mailing list is now cc'ed in. What confuses me, however, it that for the average the numbers on the right seem to indicate the log odds ratio (i.e. 0), but the poly...

Hello Michael and Wolfgang, thank you very much for your replies! I changed the height argument and I think that worked, great! As for addpoly() - the metafor manual only gives an example for a meta-analysis that was run with...

Thank you very much, Wolfgang - this worked very well! (Previously I had not specified the standard error, hence it didn't work...) I have to follow-up questions, however. 1) How can I add a summary polygon to this plot...

Hello again, thank you, Michael! I am trying with the addpoly.default (see below) command but nothing at all happens? Like, the forest plot is created but no polygons appear in the plot, even though I am not sure why...
