[R] Help in meta-analysis (URGENT please)

[Michael Dewey]

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?
