[R-meta] Meta analysis subgroups
Dear Michael Thank you for your email. and sorry about that. I have to variables, say X and Y. 1. The X has two categories, let's say a and b, so you can calculate Mean and SD for group *a* and group *b*. 2. The Y has two categories, let's say *c* and *d*. So you can calculate Man and SD for group a and group d. I have run a meta-analysis separately for both X and Y using the meta package. Now I want to run a met-analysis for X differences associated with Y. Is it possible? or I need to consider other statistical procedures? Here is the excel file Thank you Julie [image: image.png] On Thu, Aug 29, 2019 at 1:28 PM Michael Dewey <lists at dewey.myzen.co.uk> wrote:
Dear Julie Sorry bit that does not make much sense to me. See comments in-line On 28/08/2019 21:42, Julie Webbs wrote:
Dear All I have two continuous variables and each has two categories as follows:
If they are continuous then they do not have categories so I am at a loss here.
X = a and b Y= c and d I have calculated the standardised mean difference (SMD) for *X* and
*Y
using meta-analysis.* I want to calculate *X* differences associated with *Y*.
That also seems opaque here.
Would you please advise me how I can do it. Here is a sample of data.
Thank
you, Julie
I am afraid your data-set did not arrive here well since you posted in HTML and such posts get mangled when they pass through the list. It might also help if you posted an example of what the differences you are seeking would look like.
X Y
Mean SD Mean SD Mean SD Mean SD
a a b b c c d d
12 1 14 2 10 0.3 18 0.1
11 2 13 0.5 11 0.1 14 0.3
10 1 12 1 14 1 16 0.2
