    Very educational and still very high-level.
    Is there guiding videos/screencasts on meta-analysis with different types of response variables, modulators and outcomes? Perhaps covering the considerations of multivariate and multilevel meta-analysis as well as composite outcome meta-analyses, such as the concept of "borrowing of strength" (BoS) in meta-analysis where one has to deal with multiple outcomes (response variables) or studies with small sample sizes.
    Thank you

    Thank you for this video! Do you have any advice on how to organzie data when doing the extracting from studies? Do you use excel or something? I want to do a meta analysis on low birth weight and mental health, but there are sooo many different tests for mental health that I cant think out a smart way to organize it in excel.

    Is it possible to forest plot odds ratios when only given the ratio and upper and lower limits? Since many studies plainly list their OR with 95%CI and p value without reporting the samples sizes. I cannot seem to find any videos regarding this and would greatly appreciate some advice.

      Hi Samuel. I recommend that you check the relevant forums for metafor. Wolfgang's website might be a good place to start: www.metafor-project.org/

    Hi, I am struggling to run a metanalysis. It is my first time. I have continuous data with mean, sample size, and standard deviation for each study (without means for control and exposure groups.) Any ideas on the appropriate argument suitable for this type of data?

      Hi, this is outside of our scope of knowledge, as the channel is run by the Oslo UseR organizers, and the individual speakers do not moderate the recordings we upload. Please refer to relevant forums or metafor's own webpage, www.metafor-project.org/

    How to change the font style of part of a string in forestplot? Specifically, I want to italicize the text (ABCX (rs1111111-X)), which is the name of one of the columns.

      Hi Yousif, I can't find anything in the metafor documentation that allows you to do that. I would recommend you check out relevant forums for metafor, or contact the package creator.

      This channel is maintained by the Oslo UseR team, and not the presenter unfortunately. We recommend you to contact the speaker directly for specific inquires. That said, the book "Doing Meta-Analysis with R - A Hands-On Guide " might be suitable for you. (bookdown.org/MathiasHarrer/Doing_Meta_Analysis_in_R/)

    • @UseROslo
      @UseROslo  2 года назад +1

      Another option in 'Introduction to Meta-Analysis' by Borenstein et al. (2009). Wolfgang has made the R code available for all the examples: wviechtb.github.io/meta_analysis_books/borenstein2009.html

      "ablat numeric absolute latitude where the study was conducted"
