Dear Sultan

One thing I would suggest is to also use the ranktest function. In my 
experience they can give different results. You also need to look at 
the funnel plot of course and bear in mind that none of these methods 
is very satisfactory unless you have quite a number of fairly 
homogenous studies to synthesise.
