[R-meta] Meta analysis subgroups

Dear All

I have two continuous variables and each has two categories as follows:

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*.

Would you please advise me how I can do it. Here is a sample of data. Thank
you, Julie

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

Dear Julie

Sorry bit that does not make much sense to me. See comments in-line

If they are continuous then they do not have categories so I am at a
loss here.

Y= c and d

*Y

I want to calculate *X* differences associated with *Y*.

That also seems opaque here.

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
