Thank you for the video , professor. I would like to know whether the "y-axis" of the prediction interval stands for something just as the x-axis shows event rate, risk ratio etc.

How to understand the ES of the subgroup is significant in CMA, and to write the confidence interval of the subgroup, which p value will we choose?

Thanks for your interest. If you wish to take the course through Columbia University this summer, visit bit.ly/3piGP7j and search for "meta" at the top. The Meta-Analysis Workshops site provides just the basic course right now. The advanced should be available in 2024.

Thank you very much for such a handy application and your effort in educating the meta-analysis. You mention that the effect size should be chosen by the fact that which direction is our favourable. However, there seems to be a mistake. When you choose a single effect direction (for example positive), all the SMDs become positive which clearly is wrong. By the way, I'm using CMA v3.

It seems that the narrator is reading a written script, because I can hear he's turning the pages. This makes the flow a little fast. I really need 100% focus.

if Tau-squared is 0, do we get any prediction interval? when I run a check on the software, it just shows that studies share a common effect size.. does it mean that there will be no PI available? thanks for all the help

Hi Sir, if Hausman test indicates that fixed model is more appropriate than random effect model, and if in that case, in data time period (T) > cross section units (N), which FEM is to be chosen: time (T) FEM or Cross section (N) FEM?

As an MD and clinical researcher for 5 years, i observed that some MDs/physicians really have no/little idea on how to run statistical tests for research (which is understandable since statistics is really not part of the MD curriculum) so they are wholly/partially dependent on their statisticians. There are times also when the statisticians have the right idea / executed the tests correctly but the clinician interpreted the methods and/or results differently. 😅😅😅

Let me add three more to the list: eyeballing funnel plots to determine whether they're asymmetric, treating Egger's test as though it detected publication bias, using trim/fill or PET PEESE on highly heterogeneous studies

So why do the majority of studies justify their review by claiming that because I² is low, effect size variations are low? We can further use prediction intervals solely for that reason and avoid making any misleading assumptions about effect size variations. Just read "Basics of meta-analysis: I² is not an absolute measure of heterogeneity., (Borenstein et al, 2017)". Thanks for the video about it too, it was really helpful.
