st: metan question

[Michael McCulloch <mm@pinestreetfoundation.org>]

Hello,
I notice that -metan- requires the following for continuous data:
	sample size,
	mean difference, and
	standard deviation (SD)
of the experimental group followed by those of the control group. This  
could be used, for example, to pool data such as mean difference in  
blood pressure before and after an intervention.

However, if instead of the sample size, mean difference and standard  
deviation, I had for both groups:
	sample size,
	mean blood pressure before intervention
	standard deviation (SD)
	
	sample size,
	mean blood pressure after intervention
	standard deviation (SD)
would it be possible to convert into the format required by -metan-?


Best wishes,
