Dear Rosa
I suggest reformatting your dataset to have four variables (a) study (2)
MSM yes or no (3) number with HIV (4) total number. Then you can use any
of the options in metafor (look for outcomes for individual groups in
?escalc) and use MSM as a moderator.
Is there any reason why you did not just do a logistic regression?

Dear all,
I’m conducting a met analysis and I usually use Revman, bur as I’m trying to
use R more and more, I would like to conduct the met analysis here, in R
(R-studio).
One off my problems, I think, is that:
1st. it’s the first time :)
2. I only have data for 1 arm as you can see on the data that follows.
ARTIGO qt tt qc tc Personal Notes qt2
Giuliani M. (2014) - - 1515 1862 only MSM. 347
Diaz A. (2015) - - - - only MSM (n=3081) 2499

Diez M. (2014) - 3599 - - n=145337
legend:
qt the number of hiv subjetcs who are not sms.
qt2 the number of hiv subjetcs who are sms.
tt the total number of hiv subjects.
qc the number of subjetcs who are sms without being hiv.
tc the total number of subject not hiv.
Is it possible to conduct a met analysis concerning the risk of hiv among MSM
relative to the ones that are not MSM?
or simply concerning the risk of hiv among MSM????
If yes, How?
Metafor? I’ve tried, but wasn’t succeed :(
Best,
RO
Atenciosamente,
