I'm not sure what exactly are you looking for but in the metan help file 
is written:
random  specifies a random effects model using the method of
 DerSimonian & Laird, with the estimate of heterogeneity being taken
 from the Mantel-Haenszel model

You can always check the ado file to see how radom effects model is 
calculated.
